Speedmaster PCE281.2058 Fits Ford 302 351C Cleveland 220cc 64cc Hydraulic Flat Assembled Cylinder Heads

Assembly Specifications Max Lift: .550 Coil Bind: .740 Intake Install: 130lbs @ 1.8 Exhaust Install: 130lbs @ 1.8 Closed Sear Pressure: 110lbs Open Seat Pressure: 300lbs The Speedmaster Ford Cleveland 3v heads are a perfect upgrade for both 2 and 4 barrel engines. We have re-designed the intake ports by raising the floor to help cut down on the massive cross-section that hampers OEM 4 barrel heads. Not only do you get more performance out of the box than OEM heads, our heads are significantly lighter since they are made of Gravity Die Cast aluminum. As another benefit, you can run higher compression with aluminum heads before the onset of power robbing detonation.
