Are the three bolts holding the heat riser in place supposed to come out once the nuts are removed? I took the nuts off of mine but the bolts/studs ain't moving. Can't see crap in there my work light is dead.
They are 3 studs with nuts. Sometimes when removing the nuts the studs will turn out also. Most times they will break off in the manifold. The heat riser requires a doughnut gasket on the exhaust pipe side and a flat 3 hole gasket on the manifold side. The heat riser should move freely.
