If its angle problem, youll have to remill the intake, making it even more narrow, and then run a thicker gasket (or raise heads with thicker gasket, losing your copmression) Pull intake and plumb a carpenters level across the heads over the valley, jack up side of car to get a bubble level to center, use a pair of angle finders (the kind that swings like a pocket knife) off the level to determine intake face degree on each side. Take these undisturbed with your intake to machine shop and habe it looked at and corrected.port match it again...bummer!
