Just one thing to add here as I will leave the build instructions to the experts. Shooting for 9.5 SCR with 64 CC heads will require a dished piston, if you are so inclined look at the KB hypers that I used on my 383 at -18 cc that should get you close with around 0.040 squish. Going with these slugs will require close attention to the ring gap settings and get them in there tight at no more than 0.002 piston to wall clearance. My 2cents
PS welcome to HotRodders...don't worry you will get some expert input here for sure, some friendly advice...careful not to bash other forums or folks you never know who's listening
