Cam Selection 360

My 1974 Dodge D200 needed a clutch. Somehow, this turned into the engine getting a refresh. I'm sure you all know how that goes.

This is a nice original survivor, and I plan to keep it that way. Might even stick with the 2 barrel.

I don't have a lot of experience in modification. Wanted to pick your brains!

Cam and lifters will get replaced with a stock type. I do notice a few kits labeled "Stock replacement", "RV", "heavy duty", etc. I'd be interested in a small bump in power if it was essentially free, as in just making a different selection in cam.

Wondering if anyone has experience with the Melling SPD-22, and if anyone knows whether or not it will work with stock heads, including exhaust valve rotators? This cam is just a hair over stock lift, not much. Just wanted to see if anyone has had experience.
Melling CL-SPD-22

Appreciate any help!
Lookin' at that truck, & what You're doin' with it, I wouldn't change a thing. Including the cam, if it looks golden & You kept track of the lifters, it IS golden. The one thing I will tell You is to be sure to have the heads cut the amount of difference between the OE head gasket thickness, & the new ones, +.010" more. Then optimize the ignition tune/curve & leave it be. Checking the cam timing is also a very good idea.
