Thanks, everybody! A LOT of information and good thoughts on this. Now I just have to decide which one to use. Someone had mentioned the thinner side gasket is not a good idea, so I checked my gaskets (Fel-Pro), and the side gasket is a full 1/4", unlike the usual thickness for the pan and valve covers. Also, Dave, mine are "full cork" (and whatever they stick it together with) and not the felt type. Thanks, all! I really appreciate the help. I've got permatex 2, 3M weatherstrip adhesive and a few others, but wasnt' sure if there was a sure no leak system, since mine have always pretty much been "sure to leak". I'll let you know what happens as soon as the rain here in southeast Missouri goes away for a couple of days.
