Default Valvetrain knocking

Ruled out: rockers/push rods

Things we are leaning towards
New ls7 lifters
*Used dual gold springs*

PTV and pushrod length were both checked and came out good.

ok poored oil on rockers and it helped alot, didnt realize earlier im not getting oil through my pushrods to lube the rockers, now i can let it run and take pushrod out and its dripping oil and bottom and the pushrod is clean through it so nothing stopping it. could i have problem with valve cover off and the pvc isnt hooked up to pull a vacum??


hope someone can help
