AFR 295cc Bullitt Big Block Ford Cylinder Heads 85cc, Solid Roller Springs

AFR`s 295cc 14 degree heads feature 100% full CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout. Recommended for more aggressive or street/strip or racing builds with displacements up to 512 cubic inches, operating up to 7400-7600 RPM. Component upgrades and machining options are available to customize AFR Heads to your specific build.

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






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.
