edit: way way too much work there BT. Just shove some allen wrenches in the suckers and be done with it.
The locking pin MUST be long enough to go completely through both sides and stick out the back of the other side. If not, It will slip off and sproing!
Also, use the shim program I attached to the one page and see if you can re-use/swap any of the old shims to get a correct fit on the ones that are out.
I get really fussy with valve clearances, I like them all to be as close to the same as possible, not just within the tolerances, closer to each other and in the range.
