Thanks for resizing! Car is looking good!

There are formulas for figuring what the cranking pressure should be. But just for conversation sake figure something between 15 and 20 times the compression ratio. So 200 would seem high unless your compression ratio is well above 10:1 and/or rings and valves are in perfect condition.

The high numbers are prolly form excessive carbon build up inside the engine on pistons, valves and heads. Good news is that there is very little dif between all the holes.

Getting your carbs adjusted may eventually burn off much of that carbon. Though a top end teardown and R&R would prolly be beneficial. But for now don’t go cheap on gas cause excess carbon can create hot spots and cause pre-ignition even with high octane fuel.
