I'm assembling my engine. The rocker assembly is original w/116K miles, cleaned and reassembled with parts in their original places. When set on top of my new Engnbldr head, the adjusting screws don't line up. I know they are often off a little, but 3 in particular seemed pretty far out. I used feeler gauges to estimate how much shimming each rocker would need to be fairly centered:

1 in: .049"
1 ex: .024"

2 in: .035"
2 ex: .035"+ (can't tell because the rocker is contacting the stem)

3 in: .043"? (same as above)
3 ex: .025"

4 in: .035"
4 ex: .045"

Ted said .025" misalignment is common, but more than that he'd get a bit nervous. Thought I'd post that here since this isn't an easy subject to find answers about.

Ted used to cut shims (using scissors) from bronze shim stock. I only see rolls of that, which are expensive, plus I'm dangerous with scissors.

I found some steel shims at McMaster-Carr. 1" OD, 5/8" ID, .025" thick. 10 pack for $4.62. Part number 3088A413. Might need a few thousandths sanded from the inside to fit, but should be close.

Is this the route people usually go, or does any outfit sell shims specifically for this purpose?

Any horror stories about using shims?
