Jim,
If you find the need to over tighten the valve cover, you might want to
change your gasket to the silicone one offered by Justin Wagner. I have
them on my 3, 4 and 6 and you don't have to tighten to the point of
distorting the valve cover in order to get a good seal. They are a great
invention and can be used over and over.
I also believe they are thicker so the extra thickness may offer you a
bit more clearance.
