i pulled the jug off and measured the cylinder and discovered it was out of round.

do your hpd kits run hot, i find my fan is always on and the light comes on now and again.

My 416 powermaxx has 210lbs of compression. Mine never runs hot either and I don't have a fan. I do run engine ice coolant. I've never seen over 160 degrees either.
