Jon it will only emulsify ('mayonnaise') if it runs in that state. Until then you will / may have pockets of water lurking most likely in the sump.
I do all I can to avoid skimming blocks and heads. It may provide a solution but it will raise your compression ratio. If it can't be made to seal with sealant or grease, I have in the past drilled out the offending opening and screwed in a plug, then re-drilled. It is not ideal but may rescue a cherished head. Of course the plug has to be flush and this is also a good way to distort the head, so you may end up skimming anyway; but at least there will be metal there to skim. If you have a better head....yes.
