Trick Flow® Twisted Wedge® 11R 227 Cylinder Heads for Small Block Ford

Twisted Wedge® 11R 227 cylinder heads represent Trick Flow's ultimate development of the Twisted Wedge® innovation, featuring Trick Flow's most efficient combustion chamber design. The combustion chamber and valve layout move the intake valves away from the cylinder walls to reduce valve shrouding, significantly improving flow at higher lift. Shallow 11° intake/13° exhaust valve angles improve piston-to-valve clearance for high lift cams and reduce chamber volume for improved compression and efficiency. High velocity runners are optimized on the flow bench and dyno proven to outperform the competition on hydraulic roller camshaft engines. Premium materials and components, along with world-class CNC processes, guarantee uncompromising quality and durability, dimensional accuracy, and balanced flow from port-to-port. Machined castings increase strength and have a billet-like appearance. Additional features include CNC-profiled combustion chambers, 2.080"/1.600" stainless steel intake/exhaust valves, Trick Flow® by PAC Racing valve springs, and titanium retainers. Twisted Wedge® 11R 227 heads have CNC Competition Ported runners with a premium high- resolution finish for ultimate performance. Cylinder heads are available fully assembled or as bare castings. Sold individually. Key Features: • 227cc intake ports and 56cc or 66cc combustion chambers • 2.080 in. stainless steel intake valves • 1.600 in. stainless steel exhaust valves • .625" thick deck • Titanium retainers • 11 degree intake valve angle • 13 degree exhaust valve angle

Chevrolet Performance Bowtie Aluminum Cylinder Heads

Chevrolet Performance Bowtie aluminum cylinder heads offer an ideal combination of street drivability and drag-strip performance. These aluminum cylinder heads provide a broad power range with ample low-end torque, along with excellent throttle response, good mid-range torque and enough top-end power to beat your competitors to the finish line. Designed for high performance applications, the Bowtie Street cylinder heads are manufactured to precise machining tolerances, with thick deck surfaces and high-velocity airflow passages. They are available in either rectangular or oval intake port configurations. The rectangular intake ports are larger in volume and have been designed to enhance high-rpm horsepower, which makes them best for vehicles that see frequent drag-strip action. Cylinder heads with oval intake ports are smaller in volume and designed for greater low-rpm torque, therefore they're best for street applications, where lots of bottom end, off-the-line power is desired. Bowtie Street Cylinder Head Technical Notes: * Made from 356-T6 aluminum * Available in rectangular or oval-port designs * Will work on Mark IV and Gen V, VI blocks * 9/16 in. thick decks * As-cast intake and exhaust ports * No heat risers * 1.55 in. valve spring seat diameter * Heli-coiled 7/16 in. screw-in rocker stud holes * Designed for use with 3/8 in. pushrods * Use intake gasket P/N 12366985 and bolt kit P/N 12367959 * Use head gasket P/N 12363414 for bores to 4.370 in. and P/N 12363413 for bores 4.470 in. to 4.540 in.
