Looks like a quality build, ARP bolts all marked after torqued. 12 pt. intake bolts, viton valve seals.
Shine a light in on dampers, see if they appear to be rubbing?
Dampers definitely appear to be rubbing on the inside of the outer spring.

Never messed with springs.

Al least I feel better that Y’all helped me find source.
Appreciate all the wisdom here.
