    Rated 4 out of 5 by from Nice fit Had to adjust the passanger side with a bfh but otherwise went in fairly easy would recomend having help as holding the starter and header was a challenge on the driver side but worth it in the end. Installed on a 80 cutlass 442 w-30 with the 350 rocket

    Rated 3 out of 5 by from WOW Hey to the guy who designed these headers.DID you know the engine has a starter? Imagine that. You had to have designed them without the starter installed, they fit so nice without the starter. Even with a mini starter, there is no room. The pipes can move 1in closer to the frame and everything would be fine. Still not too bad for the price. Just have to massage them a little.

    Rated 1 out of 5 by from Do NOT buy these for a 5.0L Cutlass Supreme!!! I bought these for our 1986 Cutlass Supreme 5.0L/307. The fit on the motor fine, until you want to put a starter on! So decided to get a mini starter... still don’t fit. After several hours with a BFH (the tube is half flat) it cleared the starter. Burnt off the coating (not sure why they can’t paint them with header paint at the factory) and painted with header paint. Went through the heat cycles on an engine stand. Went to put the engine in the car, and both sides hit the frame. Drivers hits on top of crossmember, and passenger hits on back of crossmember. 3 times in and out, several more BFH hits, and the fit. Would NEVER recommend these headers to anyone!!

    Will this work with a 307 Olds V8 with 7a heads?

    Asked by: TonyRodriguez
    Please check the fitment tab on the web page to confirm it will fit your vehicle. It should work, but you need to verify.
