Product Description

AFR 180 SB Chevy LT1 Street Ported Cylinder Heads - (AFR-0908)

The Small Port, High Velocity Torque Monster

These AFR 180cc LT1 Eliminator Street heads are emissions-legal (CARB E.O. #D-250-2 for engines up to 1994), and are available in the LT1 angle plug version only. These heads feature a 55cc to 65cc combustion chamber (must specify) with a 64cc exhaust port and a 3/4 in. thick head deck (ideal for nitrous or blower applications). Standard valves are lightweight 8mm, 2.020" intake and 1.600" exhaust with AFR's hardened ductile iron interlocking valve seats.

Their exceptional flow characteristics, ideal operating range of idle to 6,000 RPM (higher rpm ranges are possible, depending on the combination of parts) 23 degree valve angle and standard valve spacing make AFR 180cc LT1 Eliminator Street heads perfect for 350 to 383 cubic inch engines. They are specifically designed for 1992-1995 Corvettes and 1993-97 Camaros and Firebirds.

NOTE: Modern hydraulic roller camshafts typically experience valve float at 6200-6400 RPM because of their fast ramp rates. We suggest you upgrade your springs to AFR part #8019 with higher spring pressures and use the “Hydra Rev Kit” to reduce chances of valve float associated with 6200 or higher RPM usage.
