I plan on sealing one of the interfaces, either the valve cover-gasket interface or the head/manifold-gasket interface. Not both because I'd like to be able to remove the valve covers easily. I figure sealing one interface should cut down on the odds of a leak by 50%
Which interface would you guys seal, and what would you use? The Right Stuff or 3M weatherstrip adhesive or something else?
Thanks.
