Glow plug replacement day!

Glow plug replacement day!
Well guys, after noticing only a 3-4 second glow time in sub zero temps, I finally got under the hood with my test light to see how many glow plugs I had out.
Turns out, at least 2 were bad and 1 was on its way. Figured I would play it safe and ordered 4 sealed Motorcraft ZD9's off ebay. A good deal I couldn't pass up for $34 total.
Sprayed some PB blaster on the plugs and let it sit for two days before the glow plugs arrived. Today was the day though and I got under the hood to finally replace em.
Now, I was told the previous owner only put in motorcraft parts and babied the thing... BULL####!!
I cringed when I pulled the back passenger side plug to discover...a champion. Now I figured this was done by the shop that did my valve seals...until I pulled the rest on the passenger side.
So far: 1 champion and 3 autolites. Thank GOD none of them were swollen...but three of them had noticeable deformation.
Out of plain curiosity I pulled the first two on the driver's side (tested good but what the hell) and found another champion and autolite. Didn't even have to pull the rest before another 4 genuine zd9s were on order...
Here is a picture of the first POFS champion I pulled next to a genuine beru:
Here is a shot of the slight deformation on one of the autolites:
Two pieces of autolite garbage:
And finally, the RIGHT plug in the RIGHT place:
Now after this was finished, I figured I would turn the key to see how it performed...and WOW! I got a whole 18 second glow time! The truck had been sitting in sub zero temps and today was a warmer day at 20*F but it cranked right over no problem.
I honestly had no hopes that it would start...otherwise I would have caught it on camera!
I'm very impressed with the old girl after today and can't wait to get the rest of the Motorcraft plugs in it.

I know how you feel. I just left Ohio after spending 2 weeks in all the snow and cold tempratures. The warmest it got was 31 the day before I left. Twice it got to 1 degree and I waited till it was 5 above before I started the 1987 6.9. She never failed to start, the first time I turned the key. I will have to admit I had put 8 motorcraft/beru gp's in, a new gp controler and made brand new battery cables to hook up to the 2 new batteries within a month of going to Ohio.

Well, its been a couple weeks now and the plugs still seem to work great! Way easier starts in the mornings and no more extended cranking.
But I did notice something when I started it up today. The usual clicking sound of my glowplug controller has gone away.
After starting up the truck, it used to click on and off for a about a minute. Also, my voltage meter isn't showing a drop anymore as it usually would when the controller would click.
Could this be a potential problem or are the glowplugs just not needing to cycle like it used to once the truck is running?
I pulled the front two plugs to check them and they are doing just fine...could I just be worrying over nothing?

Mine is the same way, I think it's because of the bad GP's that it clicked so much. I have an LED wired to the power side of my controller so I know the plugs are on. when I turn the key, they come on. The WTS light will shut off after 10-15 seconds and I will start the truck but the glow plugs will remain steady/on until about 5 seconds after the truck is running. Sometimes they will pop on again 1 or 2 times after for a second or two.
