stock lifters with a upgraded cam will cause noises in older motors. Newer motors dont seem to be bothered as badly as the older ones. It used to be a 50/50 chance that when you installed a cam you either got away scott free or had to pull heads and replace the lifters with LS7 ones

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
I have a 6.0 with a 232/236 .612 / 618 113 +2 with dual springs and have no noise but also had heads and valve train setup properly and clearenced
well i think i may have found my problem. i went back to the guy that i had tune my truck for me and he done some tinkerin on it and he put it on the dyno just to see what numbers i had, what he found was shocking, 1st pull it made 165 hp and the second it only made 177hp to the rear wheels. both he and i were speechless. After scratchin are heads for a few minutes he asked me if i degreed the cam right and i asked him how do u degree a cam, haha. I told him that i just put it in there with the dots lined up on the cam and crank gear ran it like that. He told me that i might have possible that i got the cam a tooth off. So i called up to Texas Speed yesterday, were i got the cam from, and told him about my problems and he said the same thing my tuner said, that i got the cam a tooth off, so im going to tear it back apart tonight and see if i got it in wrong and go from there.
