I replaced my injectors over the weekend. everything went well and generally I did not have any problems. Thanks to all of the information gleaned from these forums.

I do have one concern though and could use some advise.
I started my installation on the Right side of the truck wanting to get the more difficult side out of the way first.
I had some black high temp silicon sealant which I used for the lower to upper valve cover sealant.

I went to the auto parts store needing some cleaning supplies and more silicon for the passenger side valve cover. I started reading the lables and noticed the gray high temp is also high torque presumably the stuff the factory used. So I picked up the grey and used it for the installation of the passenger side valve cover.

So my dilemma is do I remove the right side valve cover and injector supply tubes to replace the black with grey silicon? Lots of work but I would rather do it now before all the wiring and accessories are installed and 2 months from now I find it is leaking.
