AFR Heads & Performance Parts

For over three decades, Air Flow Research has designed and manufactured cylinder heads, valves, rocker arms, intake manifolds and other performance parts that exceed OEM specs for durability and performance. It’s made them a preferred source for parts for some of the fastest race cars and most high-performance street machines to be found anywhere.

This is your destination to find high performance cylinder heads for Chevrolet Vortec and LS engines, older small block and big block Chevrolets, along with Ford small block heads. Heads are ready to install and bolt up, with no porting, relief or valve job needed. To round out your engine build, AFR also offers Eliminator Series aluminum intake manifolds with extra coolant ports installed for custom cooling system setups, as well as phenolic carburetor spacers, replacement rocker studs and stud girdles, valve cover gasket sets, valves and valve springs, exhaust header gaskets, head bolts and studs, valve covers and even engine assembly lube. With enhanced flow, top quality construction and materials and exacting specs, AFR heads and performance parts are found on some of the fastest machines in the United States, and for a good reason – they deliver better performance and better quality than just about anything on the market for Chevrolet or Ford engines.
