5 bolt valve cover leaks

steve, what valve covers do you have? also, are they machined flat on the bottom or do they have the gasket groove around the bottom.

every leaker I have always had was an easy fix with the moroso gaskets that you spoke of. so much so that I just started using them to start with.

I have the fabbed aluminum Mancini valve covers and have had zero leaks with said gaskets on them.
