Just did a valve clearance check. Tight as a drum, all four. Both
right hand sides are size 270 and no clearance left. Left exhaust
is a 260, no clearance, and left intake is not marked or is worn
off, feels the same as the 270's. How far down can I purchase
without going to far. I do not really want to purchase a big
assortment if I don't need to. Thanks for the help.

I broke down and ordered one as well, but not for geo projects. How could I
resist? It is an accurate model of my pre-modified 2002.
Peace!

Are you sure you're at TDC on the correct stroke when you measured?
I would have thought the engine would be running very poorly if there
were absolutely zero clearance on all valaves. But perhaps not, as
I've never let an engine get that far gone.
My manul shows valve clearance range at .1 - .2 millimeters for
intake and .15 to .25 millimeters for exhaust. I've always just
subtracted the difference between measured clearance and target
clearance from my existing shim to figure what size I needed to
order. Doin't know what happens when you get to zero, as I don't
know if the seats can wear such that you would have to subtract
additionally just to get back to true zero, if you know what I mean.
At any rate, I believe the shims are sold in .05 mm increments. For
the one with the size worn off, the best thing to do is to put a
micrometer on it to determine its true thickness. My opinions only.
