And you jiggled the crank a little clockwise and counter-clockwise to make certain that the piston is at TDC, right? And no air gap under the rule at the block deck, right?
OK, now it'll be interesting to see what the other 3 corners look like.
This is one of the cornerstones of having a good build and not having a good build. The more information you can put together about various pieces in the motor, the better your choices will be for parts that contribute to the combination.
