You will have to remove the left hand heat exchanger to be able to access the air injection nozzles. Any heat exchanger is best removed by heating up the nuts holding it on with oxy-acetlene to cherry red and immediately turning the nut off.
Hit the nozzles where they enter the heads with PB Blaster or Kroil before attempting to turn them out. I had a nozzle gall and destroy the threads. If this happens the hole will need to be re-tapped for a pipe plug.
All in all, the job should take 2-3 hours but when you are done your car will have lost 20 lb and gained better access around the engine compartment.
