Mullins Race Engines Aluminum 23 Degree Heads
These heads have dominated dirt oval track racing from a 23° stand point for years now.  The power it makes, matched with the driveability is 2nd to none.  It has set multiple track records and won countless national and regional championships.  What sets it apart is the quality.  The quality of the head casting, all the machining, and the parts we use.  There are store bought heads out there that are cheaper, but they are not setup and built for endurance type racing.  China does not build the quality of parts needed for the severe environment we put them in.  When you match high quality parts and workmanship, you get a winner like the Outlaw Head
