Tryoung, you can scrape with a good flat scraper (small wood chisels work well)or even with a razor blade. Pay close attention to the bits left around the studs. Wiping down with acetone or lacquer thinner won't hurt, but if it is good and clean the wiping down really isn't necessary with non-silicones such as P#2.''
Yes I would get a new gasket and they are pretty standard in most auto parts houses.
