These adapters allow almost any possible com - bination of early (o-ring) or late (rubberband) manifolds and heads to be converted to the superior sealing 78-85 style rubberband intake seals and clamps. Kit includes 4 standard adapt - ers and 2 stroker adapters. Standard adapters also work great on damaged o-ring style heads or cylinders. Stroker adapters convert most o-ring manifolds to stroker length.
