Now you would hit me with this so early in the morning ( head not screwed on wright yet), Yea they think that little bimetal spring is made of gold . And setting here trying to remember where the counter wright sets qwhen the butter fly is in the rest possession , i am thinking to the rear and when the engine revs up it move forward to allow the exhaust gasses to flow out .as for the spring the tang that goes on the pin faces forward and the butterfly should be in the closed possession. the spring hold tension on the butter fly for the closed possession. . Now a word to the wise here and this will save ya headaches DO NOT TIGHTEN UP THE 4 BOLT on the exhaust manifold till after ya have it bolted down to the head and tightened . Now there have been times that even then ya may have to have the two manifolds milled flat to get a good seal . Also make sure that in the intake manifold that the area below the butterfly is cleaned out of all carbon and rust as this will allow the heat riser to do it's job much better and allow for faster warm up of the intake .
