Pro Comps are a good choice only IF you are not interested in advancing the horsepower output much.
They are aluminum so, they look better and will weigh less than cast iron OEM heads however, only make slightly more power than a decent pair of "big valve" regular OEM castings.
From what I read from your posts, it seems you have thought of extending the AMOUNT and range of horsepower so, these Pro Comps are NOT going to be a good option for you.
They are NOT a racing type head...!
EDIT: In your situation, I would use the Aluminum SCJ's from FRPP.
