Pull all the plugs, fill the cylinders with penetrating oil, then put the plugs back in. Let it sit for the day. When the time comes, drain the sump oil and replace it with 30wt which has been prewarmed. Pull the plugs again, then try to hand-crank the engine to loosen it up. Yes, it will make a mess. You can clean that up.
THEN.... strip the engine and have the block boiled and magnafluxed... flatheads are notorious for cracks in their blocks. These have to be fixed or a new block found. Old-time engine-builders can be invaluable here. In any case, new pistons and rings should be invested in, never mind a professional valve job and having the crankshaft inspected and turned and having the bearings changed. You get the idea.
