figuring numbers with shims and clarification

if an intake valve has .06mm clearance with 2.45mm shim 
2.40mm shim would bring .06mm up to .11mm?
just looking for clarification that's all

thanx in adv

Yep,  thinner shim = bigger gap

thank you, Warren!! Am  I doing the math correctly though? each step with shim size  = .05mm ??

You are doing the math correctly.  A thinner shim will provide more clearance.  The number on the shim indicates the thickness in 1/100 of millimeters.  As a caution, use OEM shims.  I have seen incorrect numbers on repro shims.
