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.

Well once the cam gear is torqued to spec and lined up with the chain to the crankshaft..... You won’t be able to turn it by hand. Your basically turning the entire motor at that point to turn the cam over.
Unless what your talking about is once you torqued the cam gear on the the camshaft the gear is not turning even without the chain on it. Then I would recommend checking the lifters, cam gear, camshaft thrust plate, amongst other things. Take your freaking time! The world will not end in a couple more hours that it take to go over things.
I may be stupid, but It sounds like your guy may have forgot to reinstall the camshaft thrust plate. Make damn SURE he has a brand spanking new one, because those bad boys can, will, and surely fail.
Anyway, just my $0.02
