Rubber gasket vs. a cork gasket

Never heard of using contact cement! Might try that sometime. Contact cement is designed to tack up before assembly. So apply and seperate for best results.

I always use 3M "Gorilla Snot" weather strip adhesive. I never glue to the head.

Real pain to try and stick gaskets to the chrome Chinese VC!

Wheel bearing grease on the side that goes to the head. Old VW trick as with them you had to set the valves at every oil change.
