Cam swap question

I'm in the process of removing everything to swap the cam and other parts. Does a cam swap require changing the cam bearings in the motor? I have not heard that it does, but I thought I'd ask.

I have changed many a cam without replacing bearings.
A damaged cam bearing area would be a different story - very rare. SO why a new cam?

Keep pushrods oriented to location, don't soak lifters.
Then with plugs out, injectors disabled crank engine to build oil pressure and pump up lifters.

When I see the price of OEM I think aftermarket.
When I see the quality of aftermarket I think OEM.

Swapping transmission and in the process of replacing the oil pan gasket and valve cover gasket due to leaks. After seeing the cam, I noticed that the last OPDA I took out had worn the cam gear pretty good. I also had a ticking lifter for a while. Also needed a brake job. So, my refresh job turned into this:

Jasper Transmission
Front brake pads/shims (Black Magic)
Front caliper seals
Front rotors turned
Rear brake pads/shims
Rear caliper seals
Rear caliper pistons
Rear caliper pins/boots
Parking brake shoes
Rear rotors turned
Crown OPDA
EngineTech Camshaft
EngineTech Lifters
EngineTech Rocker Arms
EngineTech Push Rods
Cloyes Timing chain kit
Timing cover seal
Fel-Pro Head gasket
Fel-Pro Head bolt kit
Fel-Pro Oil pan gasket
Fel-Pro Rear main seal
Fel-Pro Valve cover gasket
Mopar Radiator
Stant Radiator cap
Mopar Thermostat
Mopar Water pump
Gates Serpentine Belt
Nylon High temp wire harness loom
Crown Throttle cable
Derale 20561 Transmission Cooler
Front Metalcloak Tube Fenders

Most of my wire harness is exposed due to the factory loom rotting off. I’m redoing it all with the nylon high temp loom. Also checking for wire damage in a few areas due to multiple codes that will not clear. If I can’t find anything, I might be calling wranglerfix.
