Crap idle after head swap

If anyone has any insight on this, please let me know. Sorry for the super low quality. It's an intermittent issue and it just so happened to be going on while I was coasting down the road. I tried to get it at a stop sign but it was being uncooperative.
I had a Z6 head on before and swapped to another Z6 head, after smashing a couple valves when my timing belt broke. The only difference is the breather box that's at the back left side near the distributor in this one it's solid, hasn't been milled out to allow for the breather. On my old head it was factory milled, though it did have a block off plate that I turned into a breather. Still I can't imagine that being the sole cause of this.
I was getting a CEL code 7 for a while but I was able to get that sorted by fiddling with some loose wiring.
Sometimes it'll idle just fine other times it'll drop damn near to zero and putter out. Not at all consistent.
I did the coolant per procedure and there's no trapped air from what I can tell.
Since I was having that code 7 before I'm suspecting it may be a shot throttle position sensor but I can't be certain since it's not throwing codes at me anymore.
