AFR 185cc SBF Renegade 20 Degree Street Heads
Air Flow Research (AFR) 1388 heads are an ideal performance upgrade for 302-393 cubic-inch engines operating in the 6,000-6,500 rpm range. Part of the AFR 185 SBF Renegade line, these heads feature ported intake runners, exhaust ports, and combustion chambers for street/strip use and are made of high-quality aluminum, allowing for a lighter-weight build. They include 8mm valve stems paired with 2.020 in. intake and 1.600 in. exhaust valves and feature a combustion chamber volume of 58cc, an exhaust port volume of 68cc, an intake runner volume of 185cc, and a ¾ in. head deck.
Viable applications for this model include Ford 4.7L/289 (1963-68), 5.0L/302 (1968-95), and 5.8L/351 (1969-95) engines featuring stud-mount rocker arms. Please note that these heads will not accept rail rocker arms and hardened push rods are required.
For over thirty years, AFR has been engineering cylinder heads that deliver unmatched flow and power output. Manufactured with advanced porting technology, AFR heads are flow-tested and subjected to a rigorous quality control process to ensure maximum performance in all applications. Whether you pilot a top fuel dragster or a street machine, AFR has a set of cylinder heads designed for you.
