Valve shim question

I have a 150 shim in place and the clearence is 9 thousands,which shin do I need?

Thanks for any help.


Give me a few minutes and I'll decipher it for you.

Is it for the ex or in side

intake or exhaust?

Yep intake,thanks Agent.

How critical is it that the valves are spot on and would it matter if a valve is one or two thousands over the six thousands,I would think not being spot on would be ok since they dont loose clearence evenly but while doing the shim thing it probley would not be a good idea to have over six thousands clearence.

Would that be correct or not?


I think the general concensus is to set them up around .004" use a 165 shim......
