I think the new Comp lifters would work just fine. 2200 is way more than enough rpm to get a little
oil slung up on them. But it certainly wouldn't do any harm to jump up to a Morel, Isky, or Crower lifter.
Yes, you will need a little wider LSA.
Let me know if you decide to buy a new bumpstick...I'm a Comp Cams dealer as well as a distributor for Jones Cams. I can do a completely custom cam for you.
