Thanks. I originally used those shims to line everything up on the iron heads after grinding down the stamped hold-downs, so I had a good collection to start with. Somewhere there is a baggie with more spares, but I can't find it!

Anyway I took a little too much off one hold-down and had to put a .010 shim back in. So the only shims other than that are the .005 on each side of each rocker Got 'em close enough.
