Aluminum Roller Rockers questions

I'm thinking since I've got better rockers, best not to go cheap on stock shafts. I like that Hughes I can buy direct, Crane I have to go through a distributor like Summit or Jegs. I'm going to contact both just to see what they have to say, but Hughes already openly gives specs on their site, they have the banana grooves for better oiling, and theirs are a bit cheaper than Crane too. If they give me the ok to use with these rockers, I'll get their hold down kits and shims as well.

I've researched Dove, and I agree they looked like they made them. Some other sources claim they've made parts for TRW (i.e. Fed Mog) so I'd not be surprised. That's welcome news to me too.

On a side note, I just found out Dove is in Columbia Station, Ohio. That's only an hour and a half drive for me, and I travel frequently up that way. Interesting.
