Torque your heads down before you go lapping the cylinders. Check head to piston outer edge clearance. If you heads are new or recently fly cut there aren't any needed corrections that lapping give you. If you have minor flame cutting on the sealing surface have the heads fly cut to remove the damage and make up the change with base shims or head gaskets. A few heat cycles on good heads will give proper seating unless the heads are warped. Most Air Cooled heads will have fuel sludge drips from the lower cylinder area simply because the new fuels are very good solvents. These leaks are common and seal almost immediately after the engine starts. Stan Wilder
