Makes a huge difference when the old ones have issues. It will probably start a lot better cold as well.  ;)

su8pack1, when you say wow, are you referring to the appearance of the injectors or the actual driving experience?  Would be interested in your comments wrt how the car now drives with the new injectors.

It started right up and ran smoothly on all cylinders after I bled off the air. In the past it was very hard to start. The cold start valve would give it that first almost start, but then I assume because the old injectors weren't spraying very good it would take a wile and many cranks to get it firing on all 6. Many fouled plugs (< 500 miles on them) and a black exhaust pipe that actually sprayed the wall black with soot behind the car.

The old injectors were probably leaking. When the car sits they leak down so you need to crank it excessively to build the static pressure back up. You may want to now adjust your CO and idle settings as they may be out because of a previous adjustment to compensate for the worn injectors.
