Sorry if this has been covered, but I couldn't find anything searching.

I just got done checking my valves. Just wondering what is considered "in spec"? I had this info when I checked them around 20K, but that was quite some time ago, and lost that info while moving.

Anyways, here are my clearance numbers, tell me what you think.

Intake:

.007/.007 .007/.007 .007/.007 .006/.006

Exhaust:

.011/.011 .011/.011 .011/.011 .011/.010

You're gonna have to pull your intake cam. But you could probably leave your EX unless you want to correct that one 10 thou valve but it is still in spec

IN: 0.008
EX: 0.011 both specs are plus/minus 1 thou

Awesome. Might as well take care of them all while I am in there. Now I have to source the shims.

Thanks, Jimbo!
