6.0 build help! Hi everyone, I’m new here. I’ve been doing lots of research and I can’t seem to figure out an answer to my problem. My buddy and I swapped his truck (2000 GMC Sierra) from a 4.8 to a Gen 4 6.0 with milled 243 heads. The heads are milled .040. The bottom end is stock. We’re using the lingenfelter box to run the 58x reluctor wheel.
The problem were having is a ticking noise. It’s not the lifters, bc they’re brand new and we’ve swapped them out already. We’ve tried multiple different length pushrods (7.250, 7.300, 7.394) and nothing will make it quieter. It runs great, with no issues which is part of the reason I’m puzzled. No matter what we change the ticking won’t go away.
Any help or or advice would be greatly appreciated, Thanks!
EDIT! I’ve attached a video of the noise

That’s what I’m thinking. I’m gonna try shimming the rocker pedestal .010 at a time and see if that makes any difference.
Yeah but all the injectors are brand new. However one of them could have failed

Yeah I know some noise is normal but it definitely shouldn’t be this loud. I may also go into HP Tuners and turn them off one by one to see if that affects the noise
Once again it sounds valvetrain related to me and ↑↑↑ the rocker making contact with the valve cover is a possibility and so is the rocker arm making contact with an aftermarket rocker arm bolt a possibility.
