Ever since I installed my ATI super damper 2 days ago I get a loud noise coming from the head at startup....I just re-checked valve lash and everything was within spec. Noise seems to go away once warm.

First heard the noice yesterday on my OEM cam gears, I just got my Golden eagles installed today and still same noise
My engine did have piston slap but I never remember it being this loud, I am supposed to go in for tune tomorrow

any ideas?
