Solid Roller lifters

Frosty I hope you don't mind me interjecting a question for Mike as it'll be beneficial for both of us as I'm considering a swap to a solid roller also.

Mike, as you know most solid rollers are billet and require a brass oil pump/dist. driveshaft. Can a cast gear be installed on the billet cam so the brass driveshaft isn't needed? Or is there another way around it? I've always heard the brass drive gear wears down pretty quick leaving brass shavings in your engine so it's not good to run on the street.
