Hi Peter, when you say no wear in the bushes have you checked the end faces? As end float tends to be the greater issue.
I guess the three holes were drilled in order improve the chances of one lining up on assembly; whether drilling out the other two would improve lubrication is hard to say. Working from memory I think the grooves in the bushes are oriented to draw oil into the cluster, and the hole allows spent oil to be centrifuged out - personally I left it alone...
I'd stress though that I use engine oil in my gearbox (as The Lord intended).
