Valve train noise

What are my chances of having a quiet valve train with:
TSP224R cam
Caddi lifters
PRC dual springs/titianum retainers
YellaTerra rockers
Pushrod length checker tool
shooting for .080-.100 preload
LS6 oil pump
??

Good chance if the preload is right .060>.080 cold or .080/.100 hot.

I would run 7.425 pushrods

Maybe I should try a
VHP #591
DUR @ .004" 286*/ 286*
DUR @ .050" 224*/224*
LIFT .551/.551
OVERLAP 58*

It seems that a lot of the people with valve train noise are running Comp lobes.

I have never heard of yella tera rockers... many people are making huge power on stock rocker arms, they seem like a really nice design. Could the valvetrain noise that people expierience be caused by the "loose" or "sloppy" stock rocker arm fulcrums? I have some 40K milie-ish stock rockers that are loose as hell.

...oh and both of my 6.0 trucks are noisy as hell, bone stock, one with 60k and one with 80k miles.

A lot of people are sending their stock rockers to Harlan Sharp and having them modified. It cost less than aftermarket and they won't spit their guts out after the mod.
