Flathead block cleaning....

[1936 ford pickup]

Hello,.

New to the Flathead V8.

Removed head and need to clean block as best I can.
Please let me know back how best to clean block.
My thoughts so far are: use razor blade to scrape off all gasket material.
Do I use wire brush with hand drill (or Dremel tool) to remove carbon buildup.
Any help with thoughts on this are much appreciated.

Thank you,

Bruce
