Installing exhaust/intake manifold nuts on a Ford Pre Crossflow can be difficult, especially with large-diameter exhaust manifolds and twin Weber intake manifolds. Our motorsport-grade exhaust manifold bolt kit makes installation and service easy. Using high-strength bolts with a smaller 5/16 12 point bolt head, tightened with a smaller 5/16" wrench or 1/4" drive socket provides easier access. Hardened small outside diameter washers are also included.
