FORD CLEVELAND PERFORMANCE ALUMINUM CYLINDER HEADS
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. There is absolutely no reason to rebuild a set of OEM castings when you can buy a lighter, higher flowing and more detonation resistant cylinder head for less money from us!
To top it all off, we offer CNC ported Cleveland heads for people looking for even more performance.
