ok so i took some measurements. I measured the amount the head was milled and i'm getting 2mm also TOP of exhaust port to deck is 28.5 mm
also when i measure with piston all the way down to deck i'm getting 2.07 on 1 side and 2..08. the pistons say 513 on top with some writing inbetween and then6450 so i'm assuming it is 64.5 mm piston.. I need to take more measurment for the porting i'm sure just wanted to put head back on and do a compression test. can you tell me where i should be on compression and also why would my rod not be even measuring to stock?
