Bad lifter? or loose rocker?

[66 Racer]

hey guys,

Well, recently my engine had developed this somewhat loud clicking, i was wondering if it was a bad lifter or just a loose rocker. it hasnt been rebuild, but the heads were about 2-3 years ago. Im thinking its a loose rocker, but i didnt know what to torque them to, i tightened them SLIGHTLY making sure there was still some play, then when i started it, the sound stoped for a few seconds, then back again.

LEt me know what you guys think, as well as the torque specs on the rockers.

thanks
