Hello everyone I have been wondering about an answer for this. I saw an install on a LS3 5th gen and the cam would not turn by hand after the cam gear was torqued down to spec for the ARP Bolts. However when the bolts were loosened the cam turned freely by hand. This was done with no heads on so spring pressure wasnt the issue. What would cause that issue because i have no answers for the guy other than pull it all back out and start over checking everything again. My guess was a lifter was in side ways or something but didnt stay long enough to verify it.
