What parts would benefit from Cryotreatment?

ANY engine part. List what would benefit.

Planned on E-Shaft, Stationary Gears, Apex Seals, and Oil Pump Internals; but what else?

Anything that is really under stress should benifit. Transmission gears are supposed to get a lot out of it.

:shrug:

I'm getting mine done locally. You should probably try a search engine for something simple... like "Cryo Treating Flordia".

Anything metal piece that is going to wear; rotor housings, metal seals, e-shaft, metal bearings, side housings, etc.

Local place by me charges by the pound with an $80 minimum so it's worth it to do as much as possible per batch.

You can do it yourself. Just use dry ice, it will take longer than with liquid Nitrogen but its much cheaper.

1. Place part(s) in freezer turned all the way down over night.

2. Place parts in an Ice chest with dry ice, ensure that you have a lot of it, place the bags that the dry ice came on top of the stuff for extra insulation and shut the chest, ensure it shuts all the way. Leave the parts in the chest until the dry ice goes away, I just left my stuff for 2 or 3 days.

3. Pull the stuff out of the chest and let it warm up to room temperature by itself.

4. Place the stuff in the oven at 400F for at least 4 hours. Turn the oven off and leave the stuff in the oven until it cools off to room temperature, you're done.

Ensure that you keep the chest in a well ventilated area.

Cryo treating works in the same manner as heat treating does. You circulate cold throughout the entire part via a forced air circulation system so that all portions of the pieces are cooled and treated evenly.

The "ghetto" way is exactly as it sounds, a bunch of BS and another reason to do just a little reseach before taking peoples' advice. Dry ice is -109 Deg F and the cryo process is -300 so you're not even close no matter how long you leave it in the "freezer". Plus there is no convection of air, no rearrangement of the latticework of molecules, etc, etc.

All you're doing is making the parts cold, there is no molecular changes occuring which is the whole point but feel free to delude yourselves

Did I mention I sell dry ice... kidding!
