Only use the valley pan, the dented circles around all the ports act as crush gaskets and thus why you should change it if you pop the intake off. The vp is used in place of just intake gaskets as they only seal the intake and supply no heat shielding or oil deflection. If you didn't seal some ports with rtv, it's no big deal as the crush zones will protect you. However if the intake works itself loose past the point where it's smashing those crush spots your going to have leaks. Personally I smeared gasgacinch all over the mating surfaces on both sides outside the crush zones and put rtv just along the outside of the ports and the front and rear seals.
