For all practical purposes, oil should be flowing to the rocker arms, after the heads were removed and cleaned. I'm thinking if I send a probe down the galley hole in the head and it stops after a certain distance, that would be an indication the head gasket is in the way. Does anyone know the distance from the top of the galley hole to the head gasket? If the gasket is correctly installed, how far should the probe travel?



thanks,

Randy
