I used the Ultra Copper. After searching threads on how to install a gasket, it seems like I shouldnt have put gasket maker all around the head surface, just on the gasket area covered. Should I start over or does this look ok? Also, I let the gasket and ultra copper sit for a couple of days, its actually been sitting for about a week uncovered in the garage. should I just start fresh and follow the instructions in the threads, or will this be ok? Do you guys use teflon tape on your oil pressure gauge adapter?
