CYLINDER HEADS
Ford Big Block 429-460
AFR Bullitt Aluminum Heads
The AFR Bullitt line of cylinder heads for the Big Block Ford features a different port shape
with a more consistent cross-section area and new valve positioning compared to the
factory pieces. This new clean-sheet design improves engine response and increases
horsepower and torque. Made of A356 aluminum castings features 100% CNC-ported
intake, exhaust chambers and high-quality components throughout. Recommended for
more aggressive street/strip or race builds with displacements up to 512 CID operating up to
6500 RPM. Note: Due to AFR's valve angle and location, custom pistons or notching existing pistons will be required. Sold in pairs.
