Intake manifold question

I had a leak so I pulled the stock ones off, had the irate's to install, got the gray stuff from ford, but my question is:
Is there a certain ambient temp that the silicone should be applied?
Of course when I tore it down, it was almost 70, and this week turned to 40's, just don't want to do this 2 times!!

As long as you let it cure I don't see an issue. If your worried about it use a heat gun to warm the pieces up before you install it.

I think I would want it to warm up some. If your motor is together and full of coolant I would just use the block heater.
