If it was 4.470 before, go 4.500, put a good set of rods in it, and work on the heads. I would go for something in the 9.5:1 range. Get some help on the cam and go.
I did a 22 Scarab with a mild 509 and it was a lot of fun. Had a customer put a blown 502 in one that was in 750HP range and he couldnt ever use the power.
