Olds 350 Heads and 455 Heads the same???

[BBSPURGEON]

I am currently rebuilding my olds 350 and I was getting a valve job done on my heads and I found 3 cracks in one head! I have an extra set of heads of 350 and 455. I stored them together and I can't figure out which is which. It appears that they are the same head! Thanks for the help!

intake ports are higher in the 455, guess they will work with a opened up edelbrock rpm manifold

smaller valve and I do believe they all have a small cc combustion camber. This would boost compression but would have a lot of exhaust pressure

Big block heads will always have a casting letter, A,C, E, F, D, etc. Small blocks will be a number or a number and letter 6. 6A. etc. They will physically bolt up but I'm not sure about an off the shelf manifold that will work.

If you are looking for big block heads try to find the "C" heads.
