thanks zip my intake has port holes in front and not in rear to drill and tap. rear looks real touchy. there is a coil holder cast in the manifold, and long , thin parting strips(raised up) right where the holes would go, the factory victors that have the right provixions have large , raised buhgs on the casting, right where the factory holes are cast. dont want to take a chance doing my manifold to get the two water p;orts. what about the other two ways i asked about thanks art
