How difficult is a cam swap?

I’m getting a little frustrated. A cam install sounds like it’s above my pay grade, and now so does advancing the cam. 2 things I hoped for, out of reach. Recurve the distributer? Probably also pro level. Sending my cam to WA from NJ sounds like it will require lots of patience I don’t have. I haven’t even figured out the cam snout/fuel pump situation yet (cheapest without sacrifice solution). I’ll have to look into pocket porting, and whatever can be done to the heads without being a rocket scientist with a machine shop.
