Ticking/knocking noise at high rpms under load

Ex manifold in new. I just replaced middle section with new holset turbo due stripped threads. How about piston pin ?

 

I just tried disconnecting air compressor intake tube from intake manifold and plugging intake manifold so i dont have boost leak under WOT. Same noise. So its not air compresor. Have to be somewhere in the valve train

 

Never found out. Just stay away from high rpms

 

Its more rpms + boost. Lets say im ar 1600 rpms and i let of accelerator peday. It wont rattle much. But If i hit accelerator and get more than 10 psi between 1400-1600 rpms it will rattle. Not before 1400.or past 1600 rpms. Its weird
Also when engine is not at normal operating temp lets say oil at 160f or coolant 160f there wont be much rattle
Sometime i think maybe is Cummins rebuld air compressor that i got installed when i did in frame. Meybe it some how boosted air geo to compressore.
Year after in frame i had front cover oil leak and with new gasket i got replaced front gears and still nothing

Even my head is new im still running original valve train since mechanic said they were good without any playbor wear and even camshafts was in good condition
