    Would you use the same technique for a head gasket?

    I had some stubborn bits of gasket that just wouldn’t budge. I put 1200 grit wet/dry sandpaper on a glass plate and did some gentle figure 8s.

    It worked well for the head, but I don’t want to risk grit on the block.

    I’ve tried the plastic razor blades and the brass brush, but there are spots where I can feel a small amount of old gasket with my fingernail.
