    Hey, this might sound stupid or what not but i was just wondering if you were to put a long stroke crank in a 172 runner like a 55m top racing one, for example. Would you have to increase the head gasket size?

    No. You space out the cylinder at the bottom with a spacer that comes with decent cranks.

    You also then do port correction.

    Coool thanks, And how come you'd have to do port correction?
