Description

The 315cc heads are AFR's largest and best flowing BBF heads! They feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings, and high quality components throughout with .250 or .625 raised exhaust port locations. These heads are best suited for large displacement high RPM Big Block Ford racing engines or radical “Pro Street” style builds. Please note, due to AFR's valve angle and location, custom pistons or notching existing pistons will be required.
