That cylinder deck should have been cleaned pre-assembly. Now when the rest of the deck is cleaned you are going to have debris down in your cylinder. Its the little stuff that gets down on top of the rings that you cant get with a shoprag that will wreak havoc on an engine. Unless you were planning on leaving the debris of the old head gasket on the deck....which is also risky
