Manifold Gasket and STud install Question

The triangles are shaped so the manifolds can slide, especially the exhaust, if its a sunday night and you need to get to work monday morning, you can take a round washer and grind it so there is 1/8 clearance where the washer fits between the manifolds. You need this clearance because the manifolds actually expand when heated and slide. If they are hitting, they are cracking....Oh and congrats on not breaking any of those studs. If you use brass nuts, they will not seize on the bolts in the future.
