Piston Choice

I was thinking to make the most of what I have with new pistons.. Don't want to shell out 1000+ for heads when mine work fine. But I would like 10:1 comp. I just don't know of the 190's will need to be modified with stock J heads. I figured they would be ok, i'm not zero decking or anything so there should be plenty of room.

But I would like to see if anyone else has done it.
