How clean does the block have to be before reinstalling heads?
In the middle of doing head gaskets. Started cleaning the block where the old head gaskets were. I have been using a razor blade and carb cleaner for the most part. Tried these lil reloc rubber bristle wheels and a fine reloc wheel. The fastest thing is the fine mesh reloc wheel. The rubber things don't do too much. I don't like the idea of the scratches that the mesh wheel leaves so I didn't use it but in a small area. I have been scraping it with a long handled razor blade. It is a slow process and I want to speed it up a bit. How clean does the block have to be? Should it be all clean like the same color everywhere, or just the areas where the gasket lays?
I have heard conflicting opinions on the reloc wheels which has made me scared to use them. I would rather err on the side of caution than screw the block up.
Anybody have any pics of what their block looked like before heads where installed?
Surely Ford or any shop that changes head gaskets doesn't spend the amount of time I have on cleaning the mating surface...
