their are several piston makers Je diamond wiseco any of those work great I have been running Je for years no issue wiseco piston are to be the hot lick right now, but your gonna need more info to determine piston to get the compression you need. Make sure you cc the heads or take to machine shop to verify how far are the piston out of the hole on the block now and head gasket thickness, on one of my setups 62cc heads ls6 with a .045 head gasket with piston out of the hole .012 gave me 11.1 so you will need that info before ordering pistons

 

Wiseco has some domed pistons for the stock bore and stroke which have a solid dome so you can take some off the top to make less compression if you want.
