Heat riser question

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.

I'm assuming once the bolts are remover the heat riser can then be removed?

Oh yeah, on a 63 impala.

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.

The bolts can remain, only the nuts need to come off to remove the riser, although due to rust and distortion, the bolts may not be well aligned anymore and put up a bit of a fight.

In the end, I replaced mine with a spacer. I did not want to worry about it getting stuck in the cold position and hurting performance.

These pics might help you see what your are dealing with. They also show the huge difference between the 2 inch and 2.5 inch manifolds.
