So here's the backstory: I took the car apart the first week in July, replaced the lifters, deleted EGR, and deleted AIR (another emissions thing on LT1 cars used to heat up the cats. Since I don't have cats...). Had a base cal done on the PCM by an experienced LT1 tuner. Finally got it all put back together, and started it up for the first time last night. Here's the result:

I only let it run for the two minutes because I got scared and shut it off. I figured out this morning that the oil pressure gauge issue was that the wire to the plug got severed somehow:
Any thoughts on the noise issue though? I was pretty confident I did the valve adjustment right, I followed the procedure on shbox.com. Being that the lifters are brand new, does it just take time for oil to get circulated through them? I also had a friend who suggested running the motor around 2500 rpm for a bit to work the lifters harder and get oil through them. They're hydraulic roller lifters, just OEM replacements (nothing special).
