Help with choosing heads for sbc
I need help with choosing a set of heads for my 350. I have a goal of 375-425hp. Motor already has a set of 1.5 roller rockers, comp mutha thumpr cam, edelbrock rpm performer intake, msd hei dizzy, and a edelbrock 1406 carb. Trans is a 700r4 with a 2500rpm stall if that matters. The motor is from a 85 suburban. I would like a set of assembled heads as I dont know enough to try and get everything my self. I also dont know what cc chambers or runners to get. I know my goal is a little high wirh out getting into the motor but I still want to try for it. Thanks for the help.
