right boys,took the head off the braap again tonight cos i knew something wasnt quite right,turns out i had a leaky gasket at the bottom or exhast port side,while ive got the head ive done a poor mans leak test to see if my valves need lapping or not,what would an exceptable leak be?its bein sittin for about 15mins so far and i have a small wet spot comin from my intake valve is this ok or should i strip the head apart and re-lap it?

cheers,
rhys.
