The valve springs included are intended for use on roller camshafts. These heads' exceptional flow characteristics, 23 degree valve angle, and standard valve spacing make them the perfect street heads for 327 to 350 c.i.d. engines in the idle to 5,500 rpm operating range (higher rpm ranges are possible, depending on the combination of parts). Eliminator cylinder heads carry CARB E.O. #D-250-2 when used on 1969-94 applications with the heat riser. They're also available for your 1987 and later engines with centerbolt valve covers and two center intake bolts at 72 degree angles; Vortec-style cylinder heads are available, too. Their dual valve cover bolt pattern is standard and their exhaust port is raised .100 over GM L98 cylinder heads.

Chevrolet Performance LSX-SC cylinder heads are developed for big-boost levels and high-horsepower engines. Undergoing a Hot Isostatic Pressing (HIP), this process is a way of casting that removes the air pockets while improving the mechanical properties of the components. LSX-SC cylinder heads are the same ones you'll see on Chevrolet's COPO 350 engine. They're available in three different configurations: as-cast; bare with CNC-machined features; or fully assembled CNC-machined cylinder heads complete with valves and springs. Features and benefits include: * Signature LSX 6-bolt head-clamping pattern * Increased deck thickness from 0.650 in. to 0.750 in. * Exhaust face thickness increased from 0.177 in. to 0.300 in. * Dense T356 aluminum material
