    Rated 5 out of 5 by from Heavier built than I expected. I bought these headers to replace a set of hedmans that had rusted out. the hedmans were a much more expensive header, but of lower quality than the Jegs headers. examples are the exhaust port flange and the collector flange they are about an 1/8 inch thicker than the hedmans, Also the thickness of the tubes, they are beefier than the hedmans, I had to modify the drivers side header as a tube was in contact with the floor board, but this is no fault of the header as I have moved my engine back and expected as much, this is when i noticed the thickness of the tubes.

    Rated 5 out of 5 by from Tight fit They are a very nice product for the money, but they don't fit exact which is usual with some long tube headers

    Rated 4 out of 5 by from Nice thick header flange These are some of the best Pontiac headers we have used in 40 years. They fit very nice, even if a long oil filter is used. Perfect for the street. Our recommendation to the manufacturer is to simply copy these headers with 1-7/8 or 2 inch individual cylinder pipes, with a 3" collector for the larger engines and/or racing and have yet another good product.

    Rated 3 out of 5 by from Great price questionable fitment Installed on a 1971 Leman's with a 428. I was doing a head gasket job on the car so I had the benefit of the heads were removed when i set them in place and mocked up. Had to relocate brake proportioning valve. Also hit passenger side frame. So marked then heated up to make indent on one of the tubes. They sound good but i do not know if i could of got them into the car if i didn't already have the cylinder heads off. Also buy a oil filter adapter gasket as well because it will have to be remove for installation.

    Rated 3 out of 5 by from Sound good, but don’t fit ‘77 Trans Am without mod I bought these for my ‘77 Trans Am with a Pontiac 400. The passenger side header fits perfectly, but the driver side is angled up toward the floorboard at the collector. The driver side will have to be modified in order to get it away from the floorboard. On a positive note, they sound amazing.

    Will these headers bolt up to an Oldsmobile 350? I was looking at a flow tech set for my 69 cutlass motor  that said it also fit a 77-81 Pontiac firebird.

    I have a 72' chevelle with a pontiac 400 engine about to be installed, well these headers fit well with the chevelle frame with no issues? Or do you recommend different headers that well work with the 72' chevelle?

    Asked by: Litty19
    Since the cross member is the same in those you should be good but they DO NOT state that is will fit with that engine swap so, PROCEED AT YOUR OWN RISK.
