Loosen the bolts that hold the intake and exhaust manifolds to the block, then loosed tne hear-riser bolts (they hold the 2 manifolds together) so that they can slide around a little. Then retighten the manifold-to-block bolts. Then retighten the heat riser bolts. Sometimes the heat-riser bolts can hold the ports off-center a little. | | |
