CM570 Cams

[Five Star]

Thoughts on where to buy a set of cams for my 02’ CM570?
Inframe was done 60k ago after 1.3 million. I had some oil leaks and we tore it on down. Cams, bearings, showing excessive wear. Engine was still strong when we inframed it, I think I turned in better cores than what we paid for in return. From the start...engine idled rough, drank oil as well.
Upgraded to newer pistons, bought new style rods from Cummins, had counter bores cut, new holset turbo, new injectors from Cummins...PX style (which I’ve already sent off and one they claimed was putting air in the system and was pby never right). New pump...etc
Just wondering about shimming the pump. Trying to find the best cams available and putting a new head on from elite diesel, or having a reputable machine shop to redo my head. The company the kit came from tried to give us “another reman” head, but copper is showing in the used bearing that are still in it, and you can see where the old cam was drug out. Very disappointed in the rebuild, as the engine ran rough, used oil, less oil pressure, etc...old motor was just leaking oil, but ran like a sewing machine. It was all original, but well taken care of.
