I couldnt tell from the video what you were referring to. I would pull the valve cover off and check your rocker arms and pull out the push rods and check to see if any are bent. As far as shops go you can try Tom, West Bend Dyno, LMT, or Clocks off racing. If you are sure its a sticking lifter, pick up a cam and some other parts then do it all yourself when you have time.
