What's are the limits on the 383HH heads as far as performance and cubic inches. Basically I guess what's the best combo for these heads?..1/8 mile only lightweight car...thx
I have friends that run 383HH. 2.375" (2.400" on 383MC & 395) that perform well on the 598 and the 632. No complaints
The engine in my dragster made 1107HP with these heads.
