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.

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

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.

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.

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.

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?
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.

Will these headers fit my 79 Trans Am with a 403ci motor with no modifications ? If any modifications what kind of modifications will it take to mount these headers on my Trans Am 79
This set only fits a Pontiac engine and is not compatible with the 403.
