Default Re: What head would you run on a SC 615?

Hello Mike,
Since no one chimed in so far......
We have run the full spectrum of BBC heads over the years on our Super Comp cars, beginning with a 468 with some Winters foundry heads in 1990, up to today with 648" engines with 12°heads. Our 12° Raptor headed engines have always run strong. We are currently running a 20° engine in one car as an experiment, can't say its a lot faster than a 12° headed engine but it is alleged to be more durable valvetrain wise. We have broken an occasional intake rocker arm on the 12° engines ( the wide offset ones) after 300 plus runs and now have them re-bodied at some interval.

Just my .02
See you at the races,
Wayne Kerr
