For the maximum high performing street/strip LS1/LS2/LS6 aluminum cylinder heads AFRs all new 230cc emission legal heads (E/O #D250-4) are hands down the best choice. Specifically designed for 1997 to present Gen-3 Chevy Corvettes, Camaros, and trucks. AFRs LSX cylinder head offers unmatched flow performance and features 2.080″ intake and 1.600″ exhaust valves with AFRs 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. AFRs LSX is a direct bolt on, no special parts required. An exclusive new modern combination chamber design with double quench pad area helps the LSX generate huge low and mid lift airflow numbers.
