Aluminum or cast iron sbc heads????
All you horsepower fiens, I'm ready to buy my heads for a 6-71 blown 383 stroker. I know aluminum is lighter and will completely disburse if the engine over heats or i spray to much nitrous. I'm learning that cast iron will last longer for my set up and i wont have to worry about melting and should be safe with nitrous. Can everybody reply and give me thier opinion?
