454 heads
Anyone have any idea what heads come on a stock 86 454 in a C30? Mainly just square or oval port is what im curious about. was thinking of ordering a new intake.

Re: 454 heads
Peanut port, though an oval intake, I've read, will work.

Re: 454 heads
Sounds like i need to find an excuse to put on a different set of valve covers so I can get the casting numbers. Lol

Re: 454 heads
mid 80's to 1990 "Peanut" ports
http://www.mortec.com/bbc.htm However mismatched manifolds work well with the smaller ports.. http://www.carcraft.com/techarticles...d/viewall.html |
