ah ok...so how they getting away with the adjustment that appears to be available in the above pics? (its looking like maybe two teeth inbetween each point, to me anyway)...no mention on either site of needing other things for clearance, saying that they dont mention the cam lift either so probably not a suprise.
Though they do stock thicker head gaskets and iirc they also used to sell other pistons aswell (cant find them now). So maybe they're aiming for a multiple part buy.
Might have to get my old engine out (put it back together haha) and have a play...
