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.

are you taking the engine out to do the heads?
I like dart/AFR and some edelbrock heads,we just need to match the flow to the cam and requirements.I would take the engine out and regasket/seal engine,pick a cam(roller hydraulic) and small runner heads that fit your needs,IE: E-tecs/dart SHP or equivalent.
