Wanna Swap Shims?

Screws in question

Are you thinking of 'set screws'?

[prometheus578]

Yeah, John, that's it

Machine set screws. All thread, no head. Goop a little silicone on the threads for good measure.
Shim buckets: Not really matched to the hole, but we all hate to have to leave a place that we've grown accustomed to. If the edges feel rough(same for the hole), just smooth it a little with some fine sand paper and clean it out. They should slide smoothly(it's a very close fit) If you have problems getting them back it... It's not so much the bucket and the walls of the hole, but rather the valve spring is too close to one side or the other.
