The Airflow Research Emissions Legal (CARB EO #D-250-2 for engines up to 1994), 180cc intake port LT1 small block Chevy cylinder heads are available in the LT1 angle plug version only. These heads feature a 55cc combustion chamber with a 64cc exhaust port and a 3/4” thick head deck (ideal for nitrous or blower applications). Standard valves are 2.020 intake and 1.600 exhaust with AFR’s hardened ductile iron interlocking valve seats. The exceptional flow characteristics, ideal operating range of idle to 6000 rpm (higher rpm ranges possible depending on combination of parts), 23º valve angle, and standard valve spacing make this the perfect street head for 350 cid to 383 cid engines and is specifically designed for 1992-95 Corvettes and 1993-97 Camaros. No special parts are required.
