440 build

I bought a 440 with the Indy 440-25 crossram 2 four set up on it that I still want to use. You don't see them every day. 11.5:1 speed pro pistons and ported 915 heads. I'm guessing that's not a good combo for the street. A little steep on compression. Would a set of aluminum heads make this useable on the street with that compression or do I have to change out to lower cr pistons. Cam was wiped so I have to do a new one. I'll check to bottom end to see if any problems with cam shavings. If crank is good ( forged ) I'll use it. If not maybe a 440 source stroker kit. I want a pretty healthy street cruiser. 500+ hp range. Any ideas on combo of cam and cr of pistons and heads needed to combo up with this intake??
