- What did you do!?!
How can I determine the shims I require if I have no valve clearance at all?

Now I'm stuck with no clearance on any shims, and the valves are all "a hair" open.
Me thinks I'm going to have to get a really thin reference shim somewhere, then spend the hours moving that shim all over the head to find my clearances. Think this will work?
Thanks!

I'd install a 200 shim (the thinnest available) and remeasure. If you don't have sufficient clearance with that, then it's time to start looking for a new head (or have new seats installed--or valve stems ground)

In the future, you should write down the shims at each valve going into the head job and tell them the limit on shim size available. That way they will measure valve end height before they start. After cutting the seats, they will grind the valve ends to try to hold the original height or at least make sure it is within service range of available shim sizes.Iv'e got no spin at all. The seats were so bad that they had to cut them pretty deep.

I was wondering the exact same thing.... Pop one/all out and measure with a caliper.... Go from there...What size shims do you have in there now?
Same time as bounty hunter mentioned, Larry C did my valve/head work and informed me exactly what I would need in shims when I got the head back.... Surprised your machinist didn't provide the same....

Measured all the shims, and they are ranging from 2.82 - 2.67 Not bad for 45 thousand k.
Wish I had done things different now...
As a side note, I may have found someone local to either exchange shims, or have him look at my head. Just waiting on a call back...
