buckaroo1 I wash the head suface dry then coat the cork gasket with RTV silicon,stick it to the head let it set up overnite. the gasket is sealed so it doesn't let oil soak thru and is like a dam to hold oil in. Put your cover on with light torque,if you need in there it;ll come off and can be put back on easily. Over time you'll have to tighten because oil and heat will make the gasket slowly give up. They once made neoprene gaskets but they got so slippery you couldn't keep it in place. Now I never tried the silicon on that neoprene gasket think that is over.
