ok so i used my z6 manifold on my b2 head to do my mpfi swap.. only thing is theres an extra coolant tube on the left top side of the manifold.. (same side as t.b.) all the coolant lines are ran but there isnt a place to run a hose from there.. any way to block it off.. or run a line into another.. i dont want to use a bolt.. kinda ghetto..
