compression and pistons

I'n building a 360 for my valiant. I bought a built short block awhile back. ITs .040 over with what looks like stock cast pistons. I was going to go ahead and use them, but something tells me I want to go a step higher. I would like to get 10: 1 or higher compression ratio without milling the heads. Is that possible.
I was looking at the kieth black pistons. They seemed resonably priced. Does anyone know which set of these pistons would get me in near that compression , there seemed like alot of different choices.
