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.
