On the intake side at the middle is the crossover heat port. around that is a U shaped cavity that extends down inside the head and ends there. What is the purpose of that?? My intake gasket is the type that blocks off the heat port hole. but part of the U cavity is still showing. It looks bad and would be a small bolt-screw trap. In addition to getting debris, oil and water held in it. Is that cavity neccessary and if not, has anyone here blocked off or filled that cavity? Today I finised assembly of the engine and now it is ready for paint.
