sbc valve noise? wont adjust right?

Hey Guys

I am Having a big problem with valve noise in a Brand new motor with less then 5 miles on Parts and rebuild? no matter how i adjust it!!

What i have is a 400 sbc .30 over with Dart pro-1 Alum heads that got a complete valve job, 11.1 forged pistons, all forged bottom end,, And It is running a 557 lift HYD camshaft plus 1.6 roller rockers and brand new comp lifters..

Yes i said bad valve noise with a HYD camshaft? I have never had this problem before, I can adjust a HYD cam in my sleep lol Butt for some reason no matter what i do this motor will not shut up!
When it is cold it seems to be somewhat quiet butt when its warm its like ever rocker in it is loose!

On every HYD cam i had i always set it them on the stand with the lifters pumped up at first and adjust them too there is some tension on the push rods, and if need be when its running ill back the rocker nut off until it starts to make noise then ill go about a 1/2 turn and its fine,

i can go a turn and a half on this motor and it don't even seem to change, it is getting plenty of oil up top also, 65 psi warm,,

Has anybody ever ran into this before? or you think the cam is bad or what?

Any info would be great thanks

Check for interference. Valve to piston, retainer to guide boss, springs stacking solid. That's a lot of lift.
