AFR 230cc LSX Cylinder Heads, 62cc Chambers, With Parts

The Ultimate Bolt-On Emission Legal Street/Strip Weapon!
For the maximum high performing street/strip LS1/LS2/LS6 aluminum cylinder heads AFR’s all new 230cc emission legal heads (ARB only, 49 state legal, not California) 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. The 230cc cylinder head is ideal for naturally aspirated 396 CI to 427 CI engines. For a wild 346 CI the 230 cc is a good choice, however some low RPM loss of torque might occur. These are available in the Big Bore setup with 62cc or 72cc combustion chambers, and also 65cc chambers in the small bore format. 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!

Important: Do not port match you intake manifold to any Fel-Pro gasket as it does not precisely match AFR heads.
Note: Milling head deck will affect flow numbers.
