Product Description

AFR 230 LSx Mongoose Cylinder Heads - (1660 - 65cc)

The Ultimate Bolt-On Emission Legal Street/Strip Weapon

For the maximum high performing street/strip LS1-LS6 aluminum cylinder heads Airflow Research's 230cc small bore Mongoose heads are a great match for your build. Specifically designed for 3.900" bore 1997 to present GEN-3 Corvettes, Camaros and GM trucks. AFR’s LSx 230 Mongoose cylinder head offers unmatched flow performance for the cross section and volume. AFR’s LSX is a direct bolt on and no special parts are required.

The 1660 LSX heads feature 2.080" intake and 1.600" exhaust valves with AFR’s iron ductile interlocking valve seats. These 230cc small bore cylinder heads are ideal for serious, naturally aspirated 370 to 383 cubic inch engines. Also a great choice for a high RPM, big horsepower 346 combination, when matched to the correct peripherals. If you have a serious forced induction LS1 powerplant, this is the large valve, big runner head for your beast. Due to the size of the intake valves, piston to valve clearance must be checked and verified with most camshaft profiles.

The AFR #1660 valvetrain consists of the severe duty #8019 valve springs (155#/410# pressures - .650" max lift) and CHE titanium retainers standard. Structural features like AFR’s trademark 3/4” thick head deck, reinforced rocker stud bosses and thick wall runners provide unparalled durability. An exclusive new 65cc combustion chamber design with double quench pads help the small bore LS engines generate huge low and mid lift air flow numbers.

Emission legal (E/O #D250-4)

NOTE: LSX bead locks and aftermarket bead locks are not interchangeable. GM made their bead lock radius and depth different. AFR locks are the same as GM LSX.
