Higher than normal compression pressures can also be due to increased valve
clearance.  The cam opening and closing ramps are very gentle, but at
cranking speed, a few thousandths less clearance can mean quite a bit.

As stated in the past, the cam journal caps wear and cause excessive valve
lash before the shims wear.  The caps can be refinished.
