Not Ranked

I'm thinking I'll get some thicker head gaskets and maybe some larger chamber heads to get down to 11:1. Anyone have any experience with Edelbrock Vr 70cc heads?

Ron - My pistons are flat-top. That's why I didn't notice when I got them that they were the wrong pistons. Apparently, in a 408W, you have to get dished pistons to get below about 11.8:1.
