The Speedmaster Ford Cleveland cast irone heads are a perfect upgrade for both 2 and 4 barrel engines. Not only do you get more performance out of the box than OEM heads, but they retain the stock look. As another benefit, you can run higher compression with these 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 better performing, higher flowing and more detonation resistant cylinder head for less money from us!
