Competition Cams has 3 cams for the carb'd engines and one turbo one. The High Energy cams are supposed to be good for street use while the Magnum one is supposed to be good for high RPM power & race cars. Their turbo cam is supposed to be the same as Mopar's Super 60
They all use slider rockers & come with new lifters.
They recommend new valve springs for cars with over 60,000 miles. Stock Mopar springs seem to work fine with the High Energy cams.

I had CL22-127-4 in my Duster after we re-built the engine, idle quality and drivability were fine, but surprisingly the car accellerated faster when I swapped back the original cam.
CompCams says that their High Energy cams are designed for engines with compression ratios no higher then 9:1, and using their cams on vehicles with higher then stock compression can decrease performance (I wonder how these would work on a turbo engine). Since my car has stock flat-top pistons and a milled swirl port head my compression ratio is higher (approx 9.5:1) and I asssumed that's why the cam didn't work well. After installing headers I put the CompCams 'shaft back in and power went up in the mid RPMs. "Powerband" doesn't seem to start until around 3000rpm. I believe my cam may be "centerlined" wrong, but I will need cam keys to change it...

Isky might still have some super high lift cams avaliable, Lunati used to list a 'shaft for the 2.2 but I haven't seen one listed since they were bought out by Holley.
Likewise CraneCams used to sell several 2.2 cams too.

Cam Sprockets
There are (at least) three different types of cam sprockets used on 2.2 engines.
Part number 5214870 is the standard cam sprocket used up to 1989, and has sets the cam at a 106º centerline
Number 5203606 was used on the Shelby HO engines and has a gives the cam a 110º centerline. (moves power to higher rpms)
The third type is used on the '89 and later engines and has a "round tooth" design that won't work on earlier engines without swapping parts..
"Common Block" and 2.5 engines also use different sprockets.
The cam sprocket is identical to the "intermediate shaft" sprocket which drives the oil pump & distributor, it's just installed backwards.

Adjustable cam sprockets are now available through some vendors. I got mine through FWDPerformance. An adjustable sprocket lets you tune the powerband of the cam to provide more low RPM torque or high RPM power. Mopar Performance used to sell offset camshaft keyways and a sprocket with 5 keyway slots but I don't think they are available anymore.
