Need help with valve lash adjustment
I recently ported my heads and put a CC 306 CAM in my car as well as headers Crane 1.6 self aligning RR's etc.... When adjusting the lash, I can get the driver side sounded nice, but on the passanger side, one of the rockers will still tick. The only way to get it to stop is to tighten it too much and that causes the car to idle VERY badly and eventually die. I have a video clip of the sound while driving away.

I hope you loosed the rocker nut off again cause that's alot of pressure on the new cam.....try swaping the noisey rocker with another one...maybe the rockers bad? is it noisey right away after you adjust it or does it take a minute? maybe the adjusting nut is not staying tight? ive seen that before on my friends '89 iroc...

It ended up being an exhast leak. A buddy came over who has the same headers as me, and he was like, dude, my car did that with those headers.... it was an on-going battle with them. (I had to dremel the hell out of them in order to get them to fit) So I"m guessing that's part of it. I'm gonna go pick up some new gaskets this weekend and try to find some sort of silicone substance that I can use on them to maybe seal it a little better. Any ideas of what works well?

How will it kill the O2's?
As long as you keep the silicone off the sensor it shouldn't effect it.... or maybe I missed something?
Ultra Copper from Permatex works real well on header gaskets. You need to check the flange flatness with a straight-edge. May have some warpage. You can get a slightly warped header to seal... just use the spongiest (thickest) gaskets you can find (cheap Mr Gaskets work nice) soak them in water so they swell a bit, let em dry and then install using Ultra Copper to help with the seal. I've used this approach a few times and it works.
If they're reasonably flat, then use a composite type gasket like Fel Pro etc..
