Powerport® Heads for Mopar These Mopar CNC Street Ported heads feature added strength around the rocker shaft and runner area, and the oil holes for the rocker shafts have been relocated for improved oiling. The 190 Small Mopar heads are compatible with all non-emissions, LA and Magnum- series 318, 340, and 360 engines; while the 240 and 270 Big Block heads fit all B and RB applications. PowerPort® Heads for Ford A460 These heads feature a high-strength casting and are ideal for large inch combinations like drag racing, tractor pulling, and other high-power engines. They have Chevy-style raised exhaust port openings and bolt patterns. A460-specific intake manifold and custom headers are required. PowerPort® Cleveland Heads for Ford 351C With its free-breathing, canted valve head design, the Ford 351 Cleveland has a lot of unrealized potential. Trick Flow picked up where the factory left off, creating cylinder heads that combine the torque of the stock 2-V heads with the high-rpm rush of the stock 4-V heads. Modifications include CNC combustion chambers, raised exhaust runners that increase flow, and a revised oil return system to improve drainback when mated to Windsor blocks. Twisted Wedge® Heads for Ford The legendary Twisted Wedge combustion chamber design increases airflow, relocates the spark closer to the center of the bore, and creates room for larger cams. Twisted Wedge 11R heads add 11° intake valves and race-inspired, high-velocity CNC runners. Twisted Wedge Track Heat® are perfect for street engines and entry-level bracket racing, while Twisted Wedge Race heads are designed for high-revving, big cube engines. *Titanium retainers. +6-bolt head bolt pattern. #18-bolt head bolt pattern. †370 lb./in. springs. ^448 lb./in. springs. ‡Titanium intake valves. ∞Has a CARB EO #.
