Today we take a look back at some early Unity Motorsports Garage videos and dig into the basics of how we flow test cylinder heads. Using @DavidVizard s IOP program we enter as much info as we can get about the runners to be flowed. We CC the ports and combustion chamber to get the port Volumes, Measure the length of the port all before we begin testing on the #Superflow flowbench. once completed we use DV's IOP to then determine what needs to be done to the port. for this test we used a OLD TrickFlow Twisted Wedge head that belongs to my friend Eric Hester of M&E engine services (The official Machine Shop of Unity Motorsports Garage) #headporting #ford #Trickflow
