These AFR 12 degree, 6-bolt LS3 heads are replacing the discontinued RHS heads that were standard on our 700 horsepower, hydraulic roller, 408 cubic inch LS engines. Although more expensive, even as porter castings, they flow better and make significantly more horsepower. The assembled heads for the 408 will have AFR valves with high RPM dual springs, titanium retainers and a 650-max lift. The 6-bolt provision can be retained if desired. A variety of other valve and spring packages are available
