What I have done with success is to put a very thin coating of Yamaha bond on both sides of the gasket. As soon as I install the cylinder I use nuts to tightly hold the cylinder in place. What I want the sealant to do is fill any small imperfections in the case, gaskets or cylinders.

I agree if you put a lot of sealant there, you are wasting your time.

BTW, once upon a time I followed an experienced Porsche mechanic who recommended CurlT on my rebuild. It eventually seeped in all the places where it didn't also have a fiber gasket. YMMV.
