 The key point to getting a dry joint with the rubber gaskets is to install them dry, with no sealant. The JHPS instructions say that in bold letters... believe it.

Everything... cover, cam carrier & gasket must be thoroughly cleaned, OIL FREE, and dry! Pay particular attention to the bottom side of the exhaust cam carrier.
It's tilted over at such an angle that more oil can run out onto the joint surface as fast as you clean it off. You'll have to remove excess oil out of the cam carrier first, then solvent-clean the joint surface to oil free and dry. Then assemble with everything dry.

Have you ever pinched a fresh/wet watermelon seed between your fingers, and shot it across the yard. That's what happens to the rubber gasket if it's installed wet, then pinched between the cover & cam carrier. And WET can be oil, sealant, sweat, hand lotion, or anything else. Install the gasket dry on dry, oil free surfaces!

Then do not over torque.
