remember to keep the manifolds parallel to the heads while installing. if needed remove the manifolds from the rest of the exhaust first,then reconnect the exhaust once the manifolds are in. quite common problem. |

| William, After 1986 Chevrolet changed the exhaust manifold bolt pattern on the cylinder heads. The first and last bolt holes are each further forward compared to the 1955-1985 casting locations. You can use either 1955-1985 exhaust manifolds or headers designed for 1955-1985 Chevrolet's as you mentioned. |
