Reply to "Checking Valves"

I have used both the full cork versions, as well as the black, composite versions. Both seem to work equally well when I slick them up on both sides with plain old automotive grease so I have a thick film on both sides. Then I hang them somewhere for an hour or so to let the grease soak in a bit to get them moist, then just wipe off the excess grease and install them.

I also have the aluminum, bolt-on, CB Performance valve covers that are supposed to leak. They don't. I aways make up new o-rings for the bolts using rubber, 5/16" ID fuel hose cut to about 1/4" thick and everything seals up just fine for me.
