360 Piston Depth

Hey all, I got a 360 for my 71 dart at a machine shop here in town. $600 got me the block bored .030 over, crank, rods with new speed pro cast pistons installed, and the rest of the rebuild kit.

I got the whole bottom end together and I went to measure the piston depth, had to use my dial caliper, but its .130" in the hole! Is this right? That would mean with the dished pistons and a 64cc chamber I would only get 8.15:1 compression....Would it be more cost efficient to get different pistons or mill the head/block deck to get to 9.5:1?

I also have a set of early 318 heads with a closed chamber, could those be ported and put bigger valves in them to get them on my 360? I would like to turn 6000 rpm with ease. Or should I spend the cash and buy some new cast indy heads.
