Valve 318 question

I will listen tomorrow to see if it continues when throttling up. Still audible at running temp. I do have the thin ones, determined today I am changing them out, they don’t seal for crap lol.

the lifters are brand new, I followed comp cams instructions before installing. I did not install new push rods or rocker arms all the original. Right now at tdc the rockers for cylinder 1 I can wiggle a little. 3 5 7 all don’t move while at tdc. I verified the torque as well.
