I'm taking all the covers off the engine case to clean, polish, and replace with Allen heads. I've gotten a majority off but there several that won't budge. The ones that case loose, loosened easily with a hand held impact driver but the ones left are stripping and one broke my impact bit. They aren't exactly in a place to get pb blaster into and vice grips are slipping off.
What would you recommend for a good brand of gasket? I remember hearing something about Athena but couldn't remember if they were good or #$%*.
