It was made in 1930, you have a really late engine , as the last one built in San Leandro was # S10536

The cold weather radiator you mentioned consist of a standard radiator with 3 pieces of cast iron trim that bolts to the top and sides, the cold weather hood rest on this trim and the cold weather dash board.
Re the position of the pistons what you are seeing is 2 on the way up, one compression and one exhaust, and 2 on there way down, 1 intake and 1 power.
Even at top dead center the piston is a couple of inches from the spark plug hole.
I think a 1/2 inch could be milled of the head of these engines to add some compression.
I have heard of a 60 that had that done and spacers were made to fit under the water pipes up top to keep alingment
