Cam Change

I'm going to be changing out the cams in my 930. I'm dropping the engine and transmission for the sake of simplicity and perform the work on a dolly. The engine only has about 6K miles since I rebuilt it, so it doesn't need anything other than the cams. My question is; Can you think of anything I'm missing in terms of what has to be removed to perform cam swap?
1. Remove turbo and IC/tubing and exhaust system.
2. Remove oil fed tensioner lines.
3. Remove turbo sump pump/lines.
4. Remove engine tin.
5. Remove engine console.
6. Remove chain covers.
7. Remove valve covers.

Of course, there's the rocker arms, cam seals and gaskets.

Also, can the camshaft spray bars be removed from the rear of engine? By rear I mean from the pulley end of the engine versus the flywheel end. I want to clean them out "while I'm in there".

Sounds like you have it. As for cleaning the spray bars, since the engine will be out, remove the spray bar plug located near the front of the engine and the plug with the banjo fitting (going to the cam chain tensioner) at the rear of the engine, and blow it out with compressed air. Again, since the engine is out, spray some carb cleaner in one end and blow out with compressed air again. This should do it unless you see some crap coming out of the tiny little holes.

Thanks DonE.

It looks like the oil cooler will have to be removed going by your recommendation. I see no way to get at that plug on the right side without removing the oil cooler.
