ah, you just reminded me of something worth mentioniing...

at walmart & hardware stores, they have a little tool for putting a razor blade in that allows you to get a better grip w/o tearing up your fingers. one was made by stanley, another generic brand at walmart was about $1 buck. I bought 2 of them (house remodel) and since having them I realized how much I could have used them while wrenching on my 5.9 motor. this tool will make your life alot easier when cleaning gasket surfaces.
