Not to hijack your thread but... I'm picking up a set of 0.30 milled (block side) X heads (63cc's) and will have to figure out an intake for mine as well. I'd rather not have to mill an intake if I don't have to. Recomendations?
Do you know if the intake face has been milled when the chamber face was milled? May or may not have fitment issues. If you have a set of crushed head gaskets of the style you are going to use in the future, slap them down, slap the heads down, put an intake down and see what it looks like........it's the ONLY way you'll KNOW for sure.
