Default 05 Suburban cam and heads

I bought an 05 Suburban with 136k miles on it, decided I wanted to upgrade it for a fun family hauler. Bought a BTR Stage 3 truck cam, Yank 3000 stall convertor, 243 heads, long tubes and full exhaust, CAI.
I pulled the motor and trans, the trans needed rebuilt, and tore the motor down to do the cam swap and heads. I took the cam out last night and it appears the first and second cam bearings are wiped down to copper. I have done several of these and never seen this problem on a motor with this few miles on it. Is there another issue causing it possibly? I also noticed the rockers and pushrods on the left head were considerably darker with burnt on old oil than the right side head.
I really don't want to pull the crank and pistons to do the cam bearings, but thinking I don't have a choice.
Any input?

Send it. The difference in the pushrods/rockers coloration from head to head is common as well.

Whats going on with this build op? I have an 04 suburban that is actually a muscle truck as well and I don't want to over cam it, but I had a similar plan to improve performance and I already have a BTR stage III truck cam to try but I was going to maybe use it along with a 6.0l swap

Difference in head appearance is due to PCV. One side gets incoming freshman air, the other is funky air as it's drawn out of the motor. Totally normal.
