Sanded them down??? Ouch! Well, whatever works, I guess, but how did you
manage to take an even cut all the way around each sleeve? (Visions of
massive leaks). The preferred way is to have the machine shop chuck them
in a lathe and remove the required amount from the step near the bottom of
the sleeve (where it rests on the figure eight gasket).
