Well, mine
still don't. Doug, you can over-think this stuff. You don't need gaskets from outer space to stop leaks.
The most likely source of the problem is the joint between head and intake, one being higher than the other. To cure the mismatch, carefully clean the mating surfaces with lacquer thinner. Apply a bead of RightStuff on both head and intake rails across the joint. Don't skimp or worry about neat. Take a strip of kitchen cling wrap and lay it over the R/S along the length of that head/intake side. Clean the valve cover rail. place a new gasket on it then place down, compressing the R/S on the head. Torque lightly and let dry 5-6 hours. Remove parts and slowly peel off the cling, it will release from the R/S. Then trim the squish-out with an X-acto. You should have one side nearly flat and the other filled with R/S like a tapered wedge. This gives the gasket an even surface to clamp on. Then apply covers according to the previous procedure. It took longer to type this than it will take you to do.
If there's no mismatch in the first place (doubtful) then you're doing something wrong in the first procedure.
