Show original supplier description

The AFR 1426-716 is a pair of A356 aluminum competition cylinder heads engineered for enhanced performance in 289, 302, and 351W Small Block Ford engines, specifically those equipped with EGR systems and aiming for displacements up to 408 cubic inches. These heads boast 100% CNC-machined intake ports (195cc), exhaust ports (58cc), and combustion chambers (58cc), coupled with a competition 5-angle valve job for optimal airflow and efficiency. The raised exhaust port location (0.125" higher) further aids exhaust scavenging. Bronze valve guides and ductile iron valve seats are also featured for durability. The deck thickness is 0.750", and the minimum bore diameter is 4.00". Installation requires moderate skill. It is important to note that these cylinder heads are not compatible with OEM pistons. Additionally, while designed as a direct-fit upgrade for specific Ford engines, new mounting hardware is sold separately and recommended for proper installation. A tech tip advises that 7/16" rocker studs are strongly recommended over 3/8" studs due to higher cam rates and RPM capabilities. These cylinder heads are intended for use on pre-pollution controlled vehicles, defined as 1965 and older U.S. manufactured California certified vehicles, or 1967 and older U.S. manufactured federally certified vehicles.
