Wrong Head Gasket installed.
I had some great work done on my roadking. 88" to 98" at Hillside Motorcycle Co. In Munnsville, NY. The guy that put the engine work back together(Behind Bars in Ballston Spa, NY) apparentlyu used the wrong head gasket resulting in too muck compression. 210psi instead of 195psi max. Just what king of damage can too much compression do to a engine?

Not sure. I would assume cam in it would play a major factor in answering your question though. Calculation of the compression ratio not just the compression reading will also aid others in giving much better answers. I.E. If correct thicker (assumed) head gasket was used your build was supposed to be X:1 compression, but it is Y:1 compression now. There are some high compression bikes out there. Run it 'til something lets got then fix it how it was supposed to be.

Need more info. Check your CCP and then with your parts and cc's of your heads use the Big Boyz calculator to do some reverse math and it should give you a idea of the HG size used and tell you your estimated CR

if your ccp is 120 I think your are too low and something is wrong. JMO

How was it the wrong gasket?
Have you talked to the guy who did the work?
At this point you seem clueless, which many are when it comes to engine work.
