I wouldn't bother w/ valve seals on the exhaust side.
Can I ask why ?
the way it was told to me is the exhaust is a push side . aka no vacuum to pull oil into the port like the intake side does
Being brutally honest with myself. Deep down there is a part of me that thinks new seals will do nothing for my oil consumption issues. But , Its cheap and I have it down far enough I have to give it a try.
