Something's still not right.....

I poured gas down the spark plug holes then into the carb-less intake, starter spun it to wash the oil and carbon out, cleaned the plugs, plugged the 4 holes in the carb's butterflies and reseated the carb. I got some gt-40p headers and got the driver's side in definitively but the passenger side is shorter by a 1/4 inch so I have some bashing to do.

Now, I go to start her up and she wont idle....again...sigh.

I pull the idle screws till they are sticking way out of the block and the A/F guage (it got coated in oil earlier so I dont even know if it still works) refuses to even register midline values. The car barely idles at a very sickly 300-500 lopey rpm with the idle screw in to the point where the transfer slot is almost uncovered (The secondary side...the transfer slots are there but not actually cut out...is this normal?). It REEKS of gas so I'm going to have to disagree with the A/F guage.

I checked all 8 wires with a timing light and all 8 are sparking and the timing is 10 degrees.

I checked the vacuum and it is a sickly 2-8 hg's heavily wobbling. I went in and definitively sealed the carb to the intake with rtv.

No change.

I sealed the top of the intake where the heads and intake meet (the front and back are already rtv'ed) with oodles of RTV.

No change

I DO remember when I first put the 1.7 roller rockers in and turned it over the first time, there was a huge bang/whack/pop sound from the passenger side. But that didnt happen at all afterward. I figured the rocker wasnt seated and it snapped into place or the double valvesprings were a bit intertwined and they snapped into place. If I had wacked a valve into the piston, it would have broken off and would continue to make noise as the debris would bounce around inside the cylinder, right?

I think I undershimmed the rockers and have them hanging open slightly. I didnt really adjust them, I just blasted them into place nice and tight and that was that.

Any ideas, guys?
