RE: [ST] Valve Shim Replacement - Another Perspective [was:Crankstorycontinues...]

Shim 'under' is better in higher rpm engines.  Shim over-bucket
engines have a disturbing tendency for the shim to be spit out in an
over-rev, &/or valve float situation.  When this occurs in a modern
negative-clearance engine, the carnage is spectacular!
