I did finally figure out the shims I needed though so I did learn a lesson....
I had to reason it out in metric ! :

what I did is take the shim size that was in it ( measured with the calipers)
and add to that measurment the feeler gauge reading which gives me the total height to the cam from the valve..... then I take the wanted valve clearance from that amount and that gives me the shim size .....
as an example my shim size that was in it was 2.82 and the feeler gauge reading was .010 adding that together gives me 2.92 I then subtract the wanted feeler gauge reading of .23 and get 2.69 and the closest shim to that is 2.70.... and that is the shim I would select for that valve.
... each valve veries a small amount in their feeler gague clearance so each one must be done seperately.
anyway I did all that and then tried to put the shim in and it wouldn't fit in the bucket.... it's like WTF ? grabbed the old shim and measured the diameter and it was 7.49.... grabbed the new shim and it was 9.49 ! it's like AURGH !!!! that was a game stopper !

...so now I wait for shims !
