TOPIC:

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.
