Never raced, brand new engine. Built with care for HP and rpm.  The top end valves, springs and gang rockers were all factory upgraded to high rpm capabilities.  The rockers were built with tool steel so they do not flex at all, and all the roller rips were upgraded to largest possible with reinforced tip holders.  This is a monster engine and it produces a lot of power. The old Belmit v4 heads produced the most powerful of any head ever built, this one will generate more with the incredibly robust upgrades the head has had done on it.
