Using 345cc on a pair of 588's for a friend. Any bigger that 540 use 345cc. Dart heads are awesome ! They are really the way to go. Anyone need stock chevy heads ? I'd like to flush out my tremendous inventory. BBB

I would want to know who made the valve springs and what valves are in it. I really doubt the valves are made of a material suitable for extended marine use.
