Default Update on tapping(need more help, I suck)

Ok, I posted before about my lt1 tapping, but I can't find the old post. Anyhow.. it's VERY loud now, and I mean very loud.. I can easily hear it over my open longtube true duals dumped mid car. It taps at rpm speed, 100% not an exhaust leak, it is definatly metal against metal or something similar.

often it wont do it right when the car starts.. but will start after about a minute of driving. Before it got this loud it wouldn't do it until I drove the car for a good 5-10 mins at least, and it was quiter.

As the rpm's raise to about 2500 or maybe 3000, I can't hear it anymore, not sure if it's cause the exhaust gets too loud, or if it stops.

Sounds like either a collapsed lifter or a bent pushrod.
