Precision Multi-Angle valve seat machining, intake and exhaust ports ported polished and flow tested on our Superflow 300 flowbench to ensure port flow and velocity is verified and pass the test. We also vacuum check our heads during our valve seat machining process to ensure the best possible valve seat concentricity is established.
