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

Take the 18 degree power leap! Ideal for drag and high-rpm circle track racing, Trick Flow® Ultra 18® 250 cylinder heads make serious horsepower right out of the box. In fact, the heads deliver higher airflow numbers than fully prepped 23 degree small block Chevy heads. These heads feature Trick Flow CNC-profiled combustion chambers and CNC Competition Ported runners with a premium high resolution surface finish for maximum flow and performance. The heads accept most current 18 degree intake manifolds, headers, and other components. They require the use of offset shaft-mounted rocker arms and a mechanical roller camshaft with offset intake lifters. Trick Flow® Ultra 18® cylinder heads are available fully assembled or as bare castings and sold individually.
