just keep in mind that VW gasser valves wont work. period.
the gas heads have an actuall combustion chamber in the head. and the valves are recessed up into the combustion chamber. so for them to be the right length to touch the cam, they have to be shorter than a diesel valve, because we have no combustion chambers, except for our prechambers, therefor making our valves longer.
