Re: WTH is up with this?
Might have bleed down enough while doing the others? Not saying this is your problem but it's easy enough to to roll it around and let it bleed down if it needs to. Also was #7 the last one you did, then #2 comes up on firing, while #7 is coming around for the exhaust (intake closed and dwelling) to open, you then put togehter, fired up and drove. I figure you did the valves one of two ways, rolled through the firing order and that put #7 second to last in sinario above or TDC#1 do eight valves then roll over to TDC#6 and do the remaining eight.
All just a thought and a hopfull easy solution to the problem. It would also explain the new stumble and back fire coming through the carb.........it would also indicate to me that the intake valve as you stated is hung open at RPM. That lifter is acting a solid lifter. One way is to back off until the rocker claters, then slowy tighten until it goes away.....then slowly go a 1/4 turn down.
I could only hope the above is your problem because that is the easy free fix!!
