Default 6.0 build help!

Hi everyone, Iím new here. Iíve been doing lots of research and I canít 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. Weíre using the lingenfelter box to run the 58x reluctor wheel.

The problem were having is a ticking noise. Itís not the lifters, bc theyíre brand new and weíve swapped them out already. Weíve 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 Iím puzzled. No matter what we change the ticking wonít go away.

Any help or or advice would be greatly appreciated, Thanks!


EDIT! Iíve attached a video of the noise

Kinda sounds like an exhaust leak Sometimes you can hear noises better from under the engine..

Confirmed tonight that itís not an exhaust leak and not any of the pulleys. The noise sounds like itís farther to the front of the motor but itís hard to tell

That can easily be injector noise.

Thatís what Iím thinking. Iím 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

Just because they are new, doesn't mean they don't make noise. That's the reason many LS engines had the factor engine covers, to cut down on noise.

Yeah I know some noise is normal but it definitely shouldnít be this loud. I may also go into HP Tuners and turn them off one by one to see if that affects the noise

seriously sounds like a exhaust leak, how did you rule it out?
take a water hose and spray around the manifolds/headers (without it being to hot of course)

Loose spark plug?

Sounds like exhaust leak,. Check it with a smoke machine, easy to make.

I would check the valve covers. If you have aftermarket rocker arms in there, then they are probably hitting inside the valve covers.

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.
