I just bought some 75cc e streets for my 30 over flat top 383....plugs are angled...cost less than 440 source heads as I needed to upgrade for a higher lift cam
I'm building my 383 now, & it's 60 over w/flat tops, but they're .105 in the hole. Do you know what your piston deck height was & is now? I'm interested in Edelbrock performer RPM heads.
