well, the block is back together with the rods and pistons in but the pistons are slightly raised from the block surface roughly 1mm?? is that normal never noticed it when taking the engine apart, will this be taken up by the gasket? also i need a headgasket with a 83mm bore and a good one at that as i plan on running lots of power any recommendations? Need one asap!

The engine was in very good condition before the build and it's a daily drive car, so I think the stock pistons are fine. Max. boost is 1.3 Bar with a GT28RS and a Flea Stage 4+ remap. I think the weakest points are the standard rod bolts, therefor changed the rods for the ZRP ones. I'm using Mobil1 0W-40 oil without any noticable consumption. Tbh I've always found the stock pistons to be the weakest.
