1971 Chevrolet Monte Carlo Exhaust Header 8 Cyl 6.6L Hedman

4 on 33 ratings
  • Features:
    • Handcrafted, Mild Steel Construction.
    • Long Tube Header Design Provides Excellent Top-End Horsepower and Torque.
    • Ball & Socket Collector Design requires No Gasket, and Allows For More Exhaust System Misalignment than Old School, Gasket-Style Header Collectors
    • Includes All The Necessary Mounting Hardware, Gaskets and Reducers (exhaust adapters)
    • Limted Lifetime Warranty On Construction, Five Year Warranty on Factory-Applied Header Coating!
    • Proud To Say, Made In The USA, Since 1954!

  • Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and MID-LENGTH tube headers for Chevy passenger cars for decades. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Small Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.

    These LONG-TUBE headers fit a variety of popular 1971-1993 Chevy Passenger cars, including Impala, Caprice and Bel Air; 1970-1977 Monte Carlo (A-Body) , and 1964-1977 Chevy Chevelle, Malibu and El Camino models fitted with a SB Chevy (Gen 1) engine. The smooth 1-5/8 in tube design provides ample exhaust flow to let your 283-400 SB Chevy engine breathe easy, and produce maximum horsepower and torque. These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.

    Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed. Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.

      They bolted right on with no issues, a perfect match. Unfortunately with the Flowmaster muffler I already had I did not notice a difference in sound.

      Would have been 5 stars if the instalation on the passenger side was not so tight!

      Great fit. Easy to install without lifting engine. High quality finish and strong welds. Also has great ground clearance. Only drops to about even with cross-member under oil pan. My 9" sump pan now hangs about an inch lower than the headers.

      It is supposed to be a direct fit for my 1978 Camaro Sport Coupe LT with a 350 and a 4 speed, but to make it fit it needed modification on the drivers side motor mount and modification to the header itself to clear my temperature sensor. The passenger side went in no problem though and it clears all my spark plugs fine, but I got long spark plug boots and it looks like a couple of places I will need 90 degree boots that are shorter to make them not hit the header pipe. They look nice at least.

      The headers fit great and cleared the frame. The outlet is below the transmission crossmember, so plan on that when you look at your exhaust. The paint burns off quickly if you are going bare, but it makes A LOT of smoke. Otherwise, sand blast and coat before you install. Came with flange gaskets and reducers.

      Do not start your engine in your garage after adding these!The black paint burns of and stinks like a nothing else!

      Great fit came on time and awesome look. I would recommend these for anyone in the market for a new set of headers.

      Great seller, quick shipping. The product was complete crap though. I have a set of the same brand and model from 7-8 years ago on my 72 C10 and they are still holding up great. The collectors on this set were bent and unusable and were obviously damaged before the coating was put on. I knew with the cheaper prices I would be getting a thinner flange and possibly making other sacrifices but these are inexcusable. I will look for other brands going forward, Hedman's quality control is obviously lacking.

      These went on a 84 c10 305 stock. The only issue I ran across was that the header on the pass side was hitting the metal fuel lines. I called Hedman and they said they have never heard of this issue. I was able to bend the fuel lines just enough to keep them from touching the header. Then I wrapped the fuel lines with heat reflective tape. No problem after about a month of driving. If you have the money get the ones already coated. I had these sand blasted and painted them with VHT Fireproof black, using their Fireproof primer also. I baked the paint on the headers using the mounted on vehicle method as recommended by Hedman, So far so good as far as the paint staying on. Just a pain to paint. Truck sounds awesome with true duals 2 1/2" pipe with 40 series Flowmasters. No cats. No H pipe or X pipe. Off road vehicle only.

      Quick delivery, perfect fit not one issue would definitely recommend, Not a huge performance gain but that wasn't expected, very neat and tidy.

      Delivery was good. Box intact and sealed. One of the down pipes had a dent the size of a silver dollar 1/2" deep. Quality???I will have to live with it.

      item came as described but had a heck of a time installing them in my 70 nova sb with a/c. Had to cutevaporator box at bottom to clear headers. The collectors were new for me but seem to seal quite well.Next time will try hooker comps

      I just ordered the wrong ones. I know several people who use these, get them powdered coated first or spray a very high temp coating/paint. Preparation is key to coating.

      I chose these partially due to pricing, but also the name. They look good, though I haven't completed the car as of yet to evaluate the overall performance factors.

      came quicker than i thought good quality even better that it came with the gaskets. love this product. i really recomend this product if you need good cheap headers

      Good sound quality. Simple install. Rusted out within 2 years so make sure to coat them with a high heat rust inhibitor

      They look and sound perfect. Fit was perfect. I recommend them to anyone who is looking for great American products!!! Fast shipment too!!!

      I snagged up these shorty headers after finding out that long tubes aren't CA legal. What an improvement in quality over the notoriously bad stock headers on my 2000's Mustang. No more exhaust leak whoo hoo!

      I'm happy with these overall. I did have some fitment issues so have to take off one star for that but with some coaxing, I finally got them all bolted up. I was happy I was able to buy american made product that didn't cost a fortune. Wish all my hotrod replacement parts were US made.

      Very well constructed product. Will fit the AMC 304 currently in my CJ-7 as well as the AMC 401 that I am building to replace the 304 when it tires out. I like the under carriage exit leaving the vehicle to appear more stock. The the stubs that bolt to the lower plates of the manifolds are included in the set and will allow the manufacture and attachment of a custom exhaust system. These manifolds are sold as " uncoated " however, they are painted with a standard quality paint to prevent rust during shipping and storage. High temp would burn this coating off rapidly, so requires stripping prior to recoating with high temp paint or coating. The price is unbeatable, particularly when Free Shipping is taken into consideration....

      These are a great value, mine have lasted over 20 years and never had any failed welds or any problems. Gas mileage improved about 10 percent and torque is noticeably greater. Never any issues with rust or corrosion and they sound great.Despite what the ad (and some rooky southern California smog techs) say, these hedders are legal in California on 6200 gvwr and higher pickups manufactuered before 1979, which are all classified as federal heavy duty emmisions vehicles and came stock without cat, egr, evap etc etc.

      CA SMOG LEGAL!!! nice product. Install is a PITA on both sides. The oil dipstick and tube will need to be removed and then modified to fit. or you can buy a flexable LOKAR setup. On the PASS side, be ready to ley over the engine and shoehorn these babies in. Getting them bolted to the mid pipe is a PITA also but overall a great product. It seals up well with the gasket provided. Just use a little high temp gasket maker on both sides to ensure a complete seal. The bolts go in easy and dont strip out like others. take your time and go easy, it will fit. They increase the sound and add som HP to the V6. Great when pair up with the DYNOMAX exhaust kit.

      The headers are not the chromed out version you see on the photo, but rather are the "Chikara" standards. However, they are good quality and you receive all the necessary equipment, bolts, O2 sensor rewire kit, individually packaged header gasket, collector gasket, and decals. If you have never done headers before than it comes with an instructional how to flyer and the steps one should take before and after attaching your equipment. Some of the black coat is coming off from being banged together during shipping, but overall I am extremely satisfied. My Talon now has better breathing and it really shows with this simple bolt on from Hedman!!
