cleanin the heads
 

Im replacing the head gasket,and wanted to know what the best thing to use to clean the heads and block thanx

I would use something that can cut grease, like brake cleaner or gas. Then rinse it off with soap and water. You would have to dry it off completely though, to prevent any slight rusting from the water.

Well probly JUST use carberator cleaners or something that will dry fast like carb cleaner and brake cleaner but soap and water i wouldnt recommend at all water nor soap burns.
