In my experience, those pistons run .018 above deck, but a 9.595 (-.005 deck cut) will cause problems when you start running a loose fitting forging at .028 piston to head. These flat tops sit .036 lower than what you've got right now. DODGE Ross Pistons 99625 Ross Racing Forged Pistons | Summit Racing
It would possibly play pretty nicely with a set of these gaskets, but they're .014 thinner, which affords a total of .022 extra clearance. I would install the pistons and measure if they come above deck first. DODGE SCE Gaskets M691239 SCE MLS Spartan Head Gaskets | Summit Racing
But... before trying to re run what you got, you want to invest in one of these and tell us what you presently have at each corner of the block. I would check each hole "just in case"... Sometimes, things get bent when pistons start kissing the heads. DIAL INDICATOR STAND TDC FINDER LS1 LS2 LS3 LS6 LSX LQ4 LQ9 4.8 5.3 5.7 6.0 6.2 | eBay
