Aluminum heads

I’m not sure why guys insist on saying a roller cam is needed to go fast. I’ve gone 9.80’s with a .520 lift Racer Brown solid lifter cam and 9.42 with a .650 Hugh’s solid lifter cam with EDM lifters. Ohhh and we broke a roller lifter bar last year in my sons engine trashing the whole engine. The comp roller lifter had around 50 passes on them.
