EVO Street Fighter Head
This is the next step up in the line of T-Man Performance EVO heads. This head comes with a 1.900 intake and 1.610 exhaust valves. It is offered in a 1.710 inlet opening or, 1.800 inlet opening. This head is available with a welded exhaust port on request for an additional charge. The head comes with fully CNC ported intake and exhaust ports and fully machined chamber to control consistency from head to head. All machined areas are hand finished to insure max flow and port velocity. This head will require a high compression piston for an 80” motor.
Head packages require your heads to be sent to T-Man Performance for work to be completed.
* When not using T-Man Performance pistons the builder is responsible for checking all valve to piston clearances.
