Holy chit, 12.5 CR on 91 pisstane gas? No need to retard timing? Good luck man, I'm hoping to run 12.5 when I start building up my K24 TSX and be able to use 93 octane daily. Also, did you have to resleeve the block to run the 12.5 CR pistons?

Are these the shelf SC7147x? If so, once you get around to claying for piston-valve clearance - let us know how much you get with the Crower cams you're running at full 50 degrees VTC (if you decide to run a K20A(2) sprocket).

Our most aggressive cam requires a 0.065" deeper intake valve relief. The shelf part comes with 0.200" intake vr. Our customs have a 0.265".
