Sweating intake manifold gasket.

I have never re-used any gasket it's just not worth the chance, again!...
you'll be into most of your day getting it off and getting everything re scraped and re cleaned up...
I've never used a torque wrench on an intake manifold. Just a 9/16 wrench...
Let all the RTV and all dry overnight at the very least refill the water and start it up drive it let it get completely cold and retighten the intake manifold...
Between the aluminum manifold and the aluminum heads, all the factory torque values are out the window anyways- I'm sure the head manufacturer has some recommended values to use, but like many others, I tend to use the "FAR" method ("Feels About Right").
