429 / 460 block Deck Height
I checked the Keith Black website. If you are thinking about the flat-top (KB #137), that piston will give you 9.7:1 with a 97cc head (like a D2VE?) and 10.2:1 with a 91cc head (close to a D3VE). The piston will still be 0.020" in the hole on your 10.322" deck height, so you won't have much quench. That sucker will probably ping.
I'm no 460 expert, but I've been a-readin' the 385 forum, so look out...
Like Luv70sFords says, the D2VE has the worst chamber of any 460 head. You'd probably do better with the D3.
You might think about using the TRW #H535P piston with D3 heads. It will give you 9.14:1 with an +.030" overbore. Run some decent cam (215-220 intake duration with 110 LSA?) and it shouldn't ping.
Or if you want some punch, zero-deck the block with either flat-top and some ported D3 heads. You'll have around 10.5:1 with good quench, but you'll probably need a fairly healthy cam for pump gas.
Like I said, I'm no expert. Check out the 385 forum archives for much more info. Good luck.
