Miss and carb tuning troubleshooting

Well I'll be damned, that flippin horse puckey PCV routing was my afr issue, curb idle also dropped down to 850 and still 650 in gear. Re-routed the pcv and threw the orange springs in before I left work, and holy hell the carb is pretty much spot on now, 14-15s cruising 40-70, some small hops to 16 if I am barely touching the gas at speed below 40, 13s when I ease on the gas to accelerate a bit and 12.5-12.8s flooring it. Hell, it doesn't miss as bad at speed either. God damn. Still pops, but most likely a header leak as stated. I am pretty darn happy right now, had a giant grin on my face driving home the whole time and wasted quite a bit of gas while I was at it lol..... hey AJ, I noticed my trans seems over filled when warm, could that cause the rpm gap when going from park to drive? Many thanks.

*edit* Still 950 curb idle, hopefully I'll get to the bottom of this.
