Aluminum headed 318s?

^^^^ yep, a small bore 340.... :) And that compression thing, that's what I wanted to do so bad to my low dollar 318, but I couldn't do it and keep the whole project under 500.00. The head gaskets I got in the kit were the .052 thick ones :( ..... I wanted the 1008 fel pro's .039 and then cut the heads .030 ..... it would have made a big difference to my motor.
