Valve shim break-in question

OK this is an engine related question, I'm trying to be a good forum citizen... please direct me to the ' CRF250L Engine Mechanical Details ' if it exists yet or back to owners forum if this Q belongs there.

I have a couple days of vacation coming up and was thinking i would check the clearance on my valve shims, except that I'll be at about 350 miles on the odo. Is it recommended to wait the 600 miles before checking? Is this a part that wears or changes as miles area accrued and therefore checking it prematurely would lead to an inaccurate measurement? Finally is it worth having the $85 box of shims from CRF's only around or will it be so infrequently needed that I might as well run down to the local Honda shop for them on an 'as needed' basis? Thank you in advance gentlemen, for your thoughtful response.
