Hi I have a set of aluminum stock vette heads. My questions are.. Does anyone know what degree these heads are ? And also these being vette heads how much abuse and horsepower can they take and hold. I know I'll probably have to change the valves and springs but I'm just curious if they'll hold to a motor built for 500 horses

those are 23 degree units just like all the rest. they have hohum airflow, BUT they have small 58cc chambers that make high compression easy without needing domed pistons. some people port them, and they do ok. if you want 500 horse power, youll probably need a blower, turbo, or nitrous injection. they are NOT a race head, and dont really make a good race head, but they are a pretty darn good street head! if you want big power, do yourself a favor and use a true hipo casting set instead.
