There is more than one mistake in play here because if you spaced the cyl further up to completely uncover the port you would end up with a lot less compression. If the piston deck to pin height was wrong and it was changed to uncover the port you would have so much less squish it may not even run.
I have seen casting flaws combined with the mass production machining tolerances being on the safe side to the extent that simply milling the parts to take away the excess safe factor results in big horsepower increases. This may be a case where unluckily all the parts were fudged on the safe side too add up to a big error end the end. I would be curious to know what the measurements would come out with a different cylinder in place.
