Iso /6 hardened oil pump drive gear

Hey everyone I'm looking for a hardened oil pump here. I have a performance oriented slant that I stuffed a .440 lift comp cam into and I've heard of oil pump gear issues. I want dome piece of mind and was looking for a hardened gear.

I look through the threads and there used to be a guy named frank with the name 66acuda but he hasn't been on here since 2014. Any and all help is appreciated. Also should I get a new don't drive gear?
