Question on compression on 4V heads

I have a set of 4v heads that i am considering putting on a 2v block. My question is what pistons would i have to use to get 10:1 commpression?

2/4 Drop
Soon to have 325hp 351 Clevo
(maybe more,in a 3600lb truck)
Backed by a C6 with a 2000 rpm stall and a 3.50 9 incher
American Racing AR-23 (series 23) wheels
Upgraded interior
Soon to have a kick @$$ stereo

You'd want pistons which would yield 8.5:1 with stock 2v heads.

That is of course assuming that you will be using *closed chamber* 4v heads.
