Just rebuilt my 600 twin with all used parts(except rings of course) and I got 138 psi mag side and 140 psi pto side. This is with one layer of head gasket. These are good numbers, correct?

I've run this sled for about 6000 miles with one layer head gasket, v force reeds, bender clutch kit and main jet one size leaner, with almost no problems. Last year I held it to the bar for to long on a long UP railroad grade when it was below zero. Should have known better.
