Which pistons?

I have flat tops in my 273 that was rebuilt before I got it. It measured out to be 7.7 to 1 with 65 cc heads. The pistons were .050 in the hole. It has closed chambered heads so even at 0 deck it would have 8.4 to 1. I plan on milling the heads to 60cc and decking the block and I'll have around 8.9.
If I was to build it for more performance I'd get dome pistons, either custom from Ross etc. or the cast ones from Egge and mill the domes to get the compression I want.
