Spray-on copper head gasket sealant. Believe it or not, they actually work quite well. The Cometics are the only other option I can think of. Then again, your existing quench with Fel-Pros is...

Mostly the dark ring below your yellow line. That's the bottom cut I was talking about rolling into the bowl with an 87% inside diameter.
