Small Block Chrysler heads

Looks like 675 are the last 3 numbers

Thanks Kim. I couldn’t read it without my glasses, I thought those were the numbers.

A decent ported 318 head can wake those tenets up really good. Charlie Servedio got some really good numbers out of a ported set.

If the OP can get those, that would be a really good help in selling these.
