I don't know what you mean by sealing up the motor...but if you mean to be putting the two block halves together....RTV is not recommended...it does not mix with oil,...is dangerous if a small piece gets into the bearing etc....I know in my gasket kits that the black RTV is always supplied, but I never use it...call up the Permatix people and have them recommend something other and better for your application

I would also suggest using the Permatex Ultra Grey, for the block halves and the cam towers.

Yep, that's what we use. Technically, Permatex 599 Ultra Gray. Also on practically all other mating surfaces: cam towers, etc.
