AFR Heads, 1620 AFR LSX 230 Mongoose Heads, LS, Bare Heads, 62cc

AFR LSX Mongoose Strip Heads are for the maximum street/strip LS1/LS2/LS6 aluminum cylinder heads AFR's all new 230cc emission legal head E/O #D250-4 are hands down the best choice. Specifically designed for 1997 to present Gen-3 Chevy Corvettes, Camaros, and trucks. AFR's LS1 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 is ideal for normally aspirated 396 C.I. to 427 C.I. For a wild 346 C.I. 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 LS1 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 unparalleled durability. An exclusive new modern combustion chamber design with double quench pad area helps the LS1 generate huge low and mid lift airflow numbers. If you need a snake chamber for that pesky neighborhood "Cobra Mustang" look no further.
