Stuck flathead V8

I have a stuck flathead V8 52 F1.
I have put one quart of marvel mystery oil and a quart of ATF in spark plugs holes. 5 of the 8 spark plug holes take all the liquid the other three stay full.
There is some oil that comes out the exhaust manifold and also some comes out the passenger side water pump. Is this normal?

The water pump leakage would tell me the block isn't good.

Nope. DOA.

Could be a bad head gasket , but chances are block is cracked .

If you put enough oil in a cylinder that was near TDC, and the rings sealed well enough, I could see some oil getting past the exhaust valve and out the exhaust. Surely this is coming out right at the block exhaust ports, not the tailpipe?

But I can't figure how you would get oil coming out the water pump, even with a really cracked block. Is there water in the block? I would guess you'd need to put a couple of quarts of oil into an empty cooling system to get it to come out the water pump.

I'd pull the heads and intake manifold and see exactly what's up.

Excellent point, and it could be that there was just enough water in the block to not come out of the pump. Oil being lighter than water would float out of the pump first.

Yes it is coming out both exhaust manifolds. When I pulled the radiator and lower hoses I got about 1 1/2 gallons of antifreeze. The mystery oil case out for awhile and now more antifreeze is dripping.
