A set of Trick Flow Twisted Wedge Cylinder Heads are the perfect way to increase the power and torque of your daily driven or street Mustang. These performance heads deliver about a 10:1 compression ratio on the stock factory short block, depending on the piston used.Twisted Wedge.
The increase in power comes from Trick Flows unique Twisted Wedge combustion chamber design that moves the intake valve to the opposite side of the camshaft. The benefit is a dramatic increase in mid-lift airflow and increased piston-to-valve and valve-to-bore clearance that allow higher lift cams and larger diameter valves to be installed without the need to alter bore size or flycutting pistons.Features.
