Thought I would update with what I found. Number 8 piston head cracked. Looks like the detonation did more than I had thought. But from the looks of the heads and the pistons there was no new signs...
instead of increasing RPM try increasing your idle airflow (base idle airflow in the airflow tab under idle). My cam liked nothing lower than 12 when I first started it after my cam swap
This might help you get a start

Decided not to open the front cover after discussing on here. Dropped the transmission and pulled the flexplate. Looks like the holes the bolts go through are a bit ovaled so maybe there was play...
Ok I was under the impression that the cam reluctor influenced ignition timing more. Im going to check over all the mechanical stuff this weekend.
The cam gear is the cam reluctor that the cam sensor reads which is used by the PCM with the crank sensor to determine the ignition timing. So if my cam is off one tooth and I believe the gear has 44...
Definitely want to check my crank cam timing now because if the cam is off a tooth that would throw off the time of for the reluctor on the cam gear. I will update what I find after I get the cover...
Engine doesn’t have a timing pointer. I have removed the heads completely a week or so ago which is how I found out that the sound was not a lifter but pre ignition because of damage to the piston...
So I tried lowering the timing a bit around idle and it helped some with the noise but it was still there a bit at idle. Also tried advancing it a bit and the sound increased a bit at idle and was...

Have a 2006 Silverado 4.8 that had a lifter going out. Replaced cam with a BTR Stage 4 Truck Cam Intake/Exhaust 0.553", 109* LSA, also installed long tube headers. After getting everything back...
