I inspected my valves at 8,500 miles and all the exhaust valves are out of spec. All the intake are in spec but on the tight side. I have the hot cams kit and will go ahead and just re shim all the valves I think. My question, is it best to shim to the middle of the specified range or on the loose end?

Exhuast clearance: .007 .011 .008 .006

Existing shims: .112 .113 .113 .110

Intake clearance: .006 .007 .007 .006

Existing shims: .114 .114 .111 .113

Note, all the shims showed slight wear and none of the size markings were legible. Measurements taken with digital calipers.

So who wants to help me figure out the new shim sizes?
