Toyota Repair: 4age valve adjustment, vernier caliper, feeler guage

Question
I just recently got the valve seats and valves recut on my 1989 gts corolla 16v 4age 1.6 liter, fwd, Ae92.  I know that i have to adjust the shims next.  The problem is that since the valves sit farther into the head and i think the shims may have been mixed up.  I can't even slide a feeler guage between the lobe and the shim.  I dont know where to go from here.  Any help would be appreciated

Answer
Setting valve clearance on these engines is a tedious/ time consuming job, it requires a vernier caliper graduated in thousands of an inch to measure the shims and some feeler gauges and as I said, lots of time and patience and maybe some new shims from the dealer, the first sep is to randomly install the shims and then the camshafts and start measuring the clearances, with a permanent marker pen mark each valve's clearance or non clearance on the cylinder head, if the clearance is too big it will need a thicker shim, the thickness is calculated by measuring the shim and adding just enough thickness using another shim to arrive at the correct clearance, easy? NO, confusing? YES. Expensive? Maybe, depending on how many shims are needed, there are 16 at about $6.00 each but by switching the shims around it may not take that many, why didn't the machine shop that ground the valves include the adjustment? It is part of the job, you may want to approach them to see if they will do this for you
