AFR’s 180cc "Street" heads are a cost effective performance choice over re-worked factory heads. They feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout. Recommended for street, towing, or street/strip engines with displacements up to 383 cubic inches, operating up to 6000 RPM. Legal for 1994 and older emissions controlled vehicles under CARB EO #D-250-2. Component upgrade and machining options are available to customize AFR Heads to your specific build (see pg. 45). To ensure trouble free operation of AFR cylinder heads & parts please view the footnotes on pg. 50 for additional information.
