World's blocks and heads are cast in the USA using special high density iron alloy, and machined on precision CNC machining centers for unparalleled accuracy. Widely used in all forms of motorsports, from drag racing, circle track dirt and asphalt to off-road and marine racing, World block and heads deliver race-winning performance and durability.

Chevrolet_Small Block
Since the late 1980s, World Products has been casting their own small block heads. Known originally as the "Dart II," this successful design was employed by bracket racers and street heroes alike for a decade. Then, in 1994 World Products superseded the Dart II with the all new Sportsman II head, followed closely by the MOTOWN, and the ubiquitous S/R heads, rounding out the most complete range of 50 State Smog Legal heads currently available. more info

Chevrolet_LS Series
LS engine swaps in muscle car era vehicles are all the rage these days and there’s a very good reason: LS engines make crazy horsepower. The exceptional airflow characteristics of LS cylinder heads enable horsepower levels that most big blocks weren’t capable of in the sixties, but deliver it in a lighter weight, small block size package.

Clearly the industry’s most efficient replacement for LS1, LS2, and LS6 cylinder Head, BMP’s LS Aluminum casting delivers more power than other aftermarket heads in its category. The highly efficient 235cc intake and 87cc exhaust ports provide outstanding flow.....hence, outstanding power.
