Description

AFR's 295cc 14 degree aluminum cylinder heads have 2.250" intake valves and 1.760" exhaust valves that move tremendous volumes of air through conservative runner volumes, spelling big torque and horsepower numbers. With combustion chamber volumes of 85cc (Milling from 76-83cc possible for $250) accompanied by 142cc exhaust ports (stock location), AFR's new 295cc is the ultimate choice for up to 512 cubic inch engines operating up to 6500 RPM. AFR's trademark 3/4" thick cylinder head deck makes them ideal for heavy nitrous or blower applications. These heads have the 1.550" OD Hydraulic Roller Valve Springs, .725" maximum lift Max RPM 6500.

Notes:
Due to AFR's revised valve location and angle, application specific AFR pistons or fly cutting your current pistons will be required.
