If
you’re looking for the world’s finest street/strip head available,
AFR’s 205 head is your answer. With 2.080 intake valves, 1.600 exhaust
valves this head moves tremendous volumes of air through conservative
runner volumes, spelling big torque and horsepower numbers. With
combustion chamber volumes of 58cc accompanied by 70cc exhaust parts
which are raised .125 higher than stock, AFR’s new 205cc is the
ultimate choice for 331 through 392 engines operating from 3500 RPM to
8000 RPM. AFR’s trademark 3/4” thick head deck makes them ideal for
heavy nitrous or blower applications. With available optional nitrous
or blower exhaust ports featuring 75cc, 80cc ultra high flow exhaust
ports.
Note: 2.080 valves will require aftermarket pistons notched for valve clearance.
