I just went and checked it then the block is still in the car but heads are of, theres no movement that I can tell from pushing around on the pistons, it looks solid, and this is with the psitons at the top of there travel. I mag particle inspceted the heads and there not cracked, theres light marks on the one piston where Id say it made light contact. It does however have on a couple of the top of a couple of the pistons a gunge like a filthy grease that you get under your car. It comes of but its really really sticky, certainly wasn there when I assembled it, im assuming this is carbon build up whilst still wet and fresh. Anyone got a good way of measuring piston height without dial indicator is there a better way, I may be getting some movement when turning the arm on the magnetic base, dont really think so but maybe
