A couple months ago I contacted Real Gaskets Tennessee (who made the very good silicone oil pan gasket) and requested that they begin making a valve cover gasket and a valley pan gasket. They asked me to mail them a new set of gaskets to use for a template.
Well... lo and behold they shipped me a set of silicone valve cover gaskets and a silicone valley pan gasket. Hopefully I can get the gaskets installed soon and begin testing. I am going to have to tell them at the very least to tone down the torque numbers but those numbers on the package really refer to the limits of the silicone gasket itself not the sheet metal valley pan or the valve cover limits. As we all know they are much lower.
I will keep you posted...
