Let MMR take your 2011-2017 Mustang GT or F150 cylinder heads to the next level with CNC porting.
When you send MMR your cylinder heads we will fully CNC port both the intake and exhaust ports to our most recent specs. Flow is greatly increased over all stages and our port designs are both dyno and track proven. HP and TRQ are both greatly increased with zero sacrifice in reliability or performance!
Finally the combustion chamber is reshaped to unshroud the valves and spark plug for reduced chance of detonation and increased cylinder head performance.
Valves are pressure tested and lapped as needed prior to reassembly to ensure a perfect seal.
Price is per pair
