ok so iam looking at my old intake manifold and i see there is a lil runner on the intake gasket running to a hole on the block right its under the middlebolt hole what is this for cuz i just put my ho manifold on and it runs bad now so could someone please tell me what its for and what i need to do to the ho manifold????? thanks

what do you mean it runs bad? Hows it running? You do realize there is a open fitting on the back of the HO manifold that needs to be closed cause you don't need it.
