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.

Appreciate any help!
