Is my block clean enough.

Here is a photo of my block. I have cleaned it with a rag and solvent, but it does not make it any cleaner than this. Is the surface that will contact the new head gasket clean enough, or does more work need to be done? If so, how would I clean it?

The product in the photo says combustion chamber cleaner, and it looks like you are only cleaning the cylinders. Are you saying it will work for the mating surface where the block contacts the new head gasket? That part is what I am concerned about being clean or not.

Is it old gasket imprinted on the metal?

That was mine a few minutes before the head went in:

Plastic blades, Permatex 80645 Low VOC Gasket Remover and acetone as a final step.

I would clean it more, until no bumps anywhere and remove as much gasket residue as possible. Just not worth getting it wrong. Takes a few hours with razor blades (be careful - for you and the head surface!) or at least with plastic blades. Last one I did the Permatex product was worthless but the 80645 is a new one I'd definitely try it.

The block face looks fine except around the lug between cylinder 1/2 intake side. Clean that yo shiny metal a bit more.

The carbon needs to come off this pistons though. Keep paper towel bits out of the dump, I managed to clog my oil pickup on my last job

See before after piston pics

Was #3 steam cleaned due to a leaky head gasket?

Yes
