Thanks for the feedback, 389. I agree on no porting for my setup since I don't plan on building the engine to twist enough to flow that much air. I intend on a simple port-matching to smooth out the runners. Regarding the compression, the 10.5:1 static will act like around 9:1 when computing the dynamic ratio up here at 5,400' elevation (I haven't calculated dynamic yet).

I just briefly searched the forum for specifics on converting '56 - '64 studs, but can you provide specifics about the components for converting? Would I use 7/16 studs similar to these with Perma-Loc nuts, stamped rockers similar to these, and hollow pushrods similar to these. Then it sounds like I'd tap and plug the oil feed holes in the block with 1/8" NPT?
