First Flathead Build

[Fortunateson]

I'm going to be doing something similar. One bank had water enter from a leaky roof via heads without spark plugs. I've been soaking in ATF and acetone. So far no movement. I thought I might flip it over, remove the pan, oil pump, and then the crank. I should be able to tap on the con rods to get some movement. Yes? Don't want to hijack but thought it might pertinent.
