I'm wanting to build up a 383 stroker engine from a donor 1978 350 engine I have. I needed to know if anyone had any recommendations on what size heads to use in order to get the correct cfm's to the intake and exhaust valves. I see different heads with different size ports and valves. I can get the parts here locally and get the engine machined but just wanted different opinions before going forward. Thanks for the help.
