intake manifold gasket and installation

And i will use the edelbrock gasgacinch on the gasket on the head and put some on the intake its self and use the ultra black silicone on the front and back ends and i will let it sit for at least 24 hours before starting it. Then hopefully i wont have to take this intake off ever again. Oh and i was also wondering... would it be a good idea to use some permatex high tempature thread selant on the intake bolts? because i noticed the threads have oil on em, so i figured it might be a good idea to use thread selaent or teflon tape on them to keep oil from coming up thru the bolts?
