230cc LSX Mongoose Aluminium Cylinder Heads 65cc Combustion Chamber. Suit Chev LS1/LS2/LS6

For the maximum high performing street/strip LS1/LS2/LS6 aluminum cylinder heads AFR's all new 225cc are hands down the best choice. Specifically designed for 1997 to present Gen-3 Chevy Corvettes, Camaros, and trucks. AFR's LSX cylinder head offers unmatched flow performance and features 2.080 intake and 1.600 exhaust valves with AFR's iron ductile interlocking valve seats. Our 230cc cylinder head is ideal for normally aspirated 396C.I. to 427C.I. For a wild 346 ci the 230 is a good choice, however some low RPM loss of torque might occur. It is available with 62cc, 65cc, and 72cc combustion chambers. AFR's LSX is a direct bolt on, no special parts required. Structural features like Air Flow Research's trademark 3/4" thick head deck, a must for blown and nitrous applications, reinforced rocker stud bosses and thick wall runners provide unparalled durability. An exclusive new modern combination chamber design with double quench pad area helps the LSX generate huge low and mid lift airflow numbers. If you need a snake charmer for that pesky neighborhood "Cobra Mustang" look no further!
