4G63 Cyclone Swap loud valve noise why?

[got-psshh]

sup i just swapped my old motor for a new cyclone motor... i've got really loud valve noise after my motor gets heated up... its valve chatter, i think, because its coming from everywher in the head.. i am wondering if its common, and how to fix it, thanks.

Do a compression check.

My "noisy valves" ended up being a bent valve.
