Suggestions on crud removal

[alexiskai]

Hi folks,

Starting an engine overhaul - new head, valve adjustments, other stuff – and I'm wondering about the best ways to remove crud. Specifically three kinds of crud:

Crud #1: Gasket remnants on both painted and unpainted surfaces. I can scrape it off, but there's always residue.

Crud #2: Brown crud on the surfaces of the water jacket. The coolant looked great when I drained it, but now that I'm taking stuff apart there's a lot of crud around the water pump. Anything I ought to do to flush that stuff out? Is it rust?

Crud #3: Residue in the holes in the block where the head studs went.

Thanks for any suggestions.
