Mullins Race Engines Dart USRA/IMCA Stockcar Heads *FULLY MACHINED BARE CASTINGS

Mullins Race Engines Dart USRA/IMCA Stockcar Heads *FULLY MACHINED & ASSEMBLED

We use this head in multiple sanctioning bodies and in multiple classes.  We prefer the dart casting over the other options in these series allow.  We take it and apply our high quality workmanship.  This includes a valve job that flows well and is concentric for a good valve seal.  All the machined surfaces get ran across our machining centers to give you a high quality product.  These heads are mass produced and we take nothing for granite.
