Hi ! , if you are changing the stem seals on the head it is always a good idea to do ONE cylinder at a time if still fitted , that way there is little chance of dropping a valve into the cylinder ( make sure the piston is at top dead centre ) . While checking the seals it is a good idea to check the oil gallery allen key plugs . These are known to leak and fill the spark plug holes with oil . If they were leaking then curing this leak will improve your oil pressure somewhat .
