Cylinder Compression Values

[TONY!]

I have only "de-carbonized" pistons once, but the engine was fully disassembled...and that is the extent of my experience with that.

As far as continuing to drive a car with that much compression (like you said IF true), pinging/detonation/pre-ignition would be your biggest concern.
Do you hear pining when going uphills? Do your spark plugs look like what illustrations show for pinging? Sometimes plugs can be a clue, but your ears should pick up on it.
Engineers want a car to be as high compression as possible without pinging problems.
Higher compression engines are more fuel efficient and more powerful (all else being equal).
