Will fit with Dart Windsor head. Requires the use of 1966 and later motor mounts and frame mounts Ford P/N D00Z6038G and because of possible chassis sag, the shock towers must measure a minimum of 33-3/4" measured between the top of the shocks. Header will fit with C-6 transmission. Will not fit heads with raised exhaust ports. See instructions for other notes. Do not use header wraps; they can cause header tube cracking from excessive heat or rust from moisture build-up and void the warranty. Breaking in an engine with ceramic-coated headers can damage the coating and void the warranty. Use cast-iron exhaust manifolds or old headers during engine break-in to prevent coating damage. Ceramic-coated headers require several heat cycles to fully cure before withstanding extreme heat.
