Help! Newly renovated engine got stuck while cranking it...

Down the sparkplug hole, and use the air to distribute it around the pistons and rings, or it will just puddle up on the exhaust side of the piston and not get the entire ring area on the cyl walls.
Like a tablespoon in each cylinder.
If it does end up breaking loose, it still may have trashed the rings.
How long the engine sat was a good question, cause if it sat for some time the oil on the cyl walls would have run off.
Turning it dry with the starter could have built up enough friction to gall the cylinder walls.
Just because you have oil pressure does not mean the cyls have oil.
That happens only when the engine is actually running, and not from the oil pump pumping.

We run the engine without spark cables to build oil pressure and get oil up the rockers. Maybe this wasn't a good way, we should have primed only the pump without the engine rotating?

Is it likely that we have damaged the rings or bearings now that the engine is kinda stuck, or is it still a chance to make it move again correctly and unharmed by using TrailBeasts advice? Just a follow up question. When you say a little oil in the cyls you mean pour some in each hole where the spark plugs go?
