Need advice on pistons for a 10.5 motor with TFS heads

I'm building a 460, I need a set of .040 over pistons. I want to run trick flow heads that have a 74cc combustion chamber volume. My max valve lift will be about .680". I want to keep my compression around 10:1 - 10.4:1. What pistons should I use?

Thanks.

You'll need a -19 to -15cc dish for 10-10.4:1 compression. Closest thing off the shelf would be...

Probe FPS -24.4cc dish +.030 or +.060
Probe SRS -11cc dish +.030 or +.080
Speed Pro L2404 -22cc +.030, +.040, +.060
Diamond -25cc dish +.030, +.040, +.060, +.080
(Diamond can be ordered with custom dish also)

The Diamond's would fit your needs the best. (+.040, custom dish, deep valve reliefs, 2618 alloy). Any other choice will require some comprimise in compression, bore, milling heads, and/or cutting deeper valve reliefs.
