  • Mullins Race Engines Dart IMCA Northern/Southern Sportmod Heads *FULLY MACHINED BARE CASTINGS

    Mullins Race Engines Dart IMCA Northern/Southern Sportmod 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.

  • Bowtie Vortec Heads
    I am a huge fan of these heads and where we can use it.  If you have a flat tappet or flattop piston rule where a cast iron head is needed, this is the head for you. We like it in 2 Barrel & 4 Barrel applications.  If the cubic inch is bigger than 362, our CNC porting program makes this head viscous.  We give you multiple options on what you can do with this head.  You will not go wrong as long as it is being used in the correct application.
  • Crate Killer Heads
    I think the name reflects that we use these on our crate killer engines.  These are stock GM Castings that we do all of our work to.  This includes installing screw in studs and guideplates, CNC Porting, Valve Job, & Milling.  For cast iron heads, these are the lightest ones available.  I really like these on smaller cubic inch engines with flattop pistons & flat tappet camshafts.
  • World Products Heads
    These Heads are our replacement with Dart not making the castings we used for a long time.  These start out as a 220cc head then we have a CNC Porting program that machines them out to 230cc.  With the porting program they run as good as our Dart head which we previously used.  We use these heads on bigger cubic inch cast iron engines with dome type pistons.  They can be used with flat tappet or roller camshafts.  We have part numbers for both options.
  • USMTS SPEC HEADS:
    These heads are used on USMTS/USRA sanctioned tracks.  It is very limited to what work can be done to keep this head legal.  We are able to take full advantage of what the rules allow with our newen valve seat machining center.  We are able to optimize the flow, keep the head legal, and obtain the best valve seal.  We also angle mill the heads then correction machine the intake flange so a standard manifold can be bolted on.  All of this work is done in CNC machines so everything fits and matches up 100%.  Matching this workmanship with the parts quality we use produces a great product!
  • WISSOTA SPEC HEADS:
    These heads are used on WISSOTA sanctioned tracks.  It is very limited to what work can be done to keep this head legal.  We are able to take full advantage of what the rules allow with our newen valve seat machining center.  We are able to optimize the flow, keep the head legal, and obtain the best valve seal.  We also angle mill the heads then correction machine the intake flange so a standard manifold can be bolted on.  All of this work is done in CNC machines so everything fits and matches up 100%.  Matching this workmanship with the parts quality we use produces a great product!
  • Aluminum Outlaw 227 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

  • MRE LS7 Heads
    These Heads are used on our LS7 Engines.  Both are used in Latemodel and NE MOD Type Racing.  We noticed a couple things early on working with the LS Platform on circle track engines.  All the available heads were to big runner wise.  They were all made for drag racing or any other form of racing.  The 2nd thing was the water was not correct which would cause overheating.  Once we figured this out, then we knew we had to design our own head.  This head turned out great, Makes awesome power, & drives good.  We also got the engines running cooler.  If you are building an LS Platform Oval Track Engine, I highly recommend these.  It will save you a bunch of headaches.
  • Aluminum 13° MOD Heads
    We designed these heads to give us an engine that drives similar to our 23° packages but simply makes more power and torque.  We keep the driveability the same by keeping the cross sectional area of the head similar to our 23° Outlaw.  With the head having a better port shape and many other advantages, it gives us the boost in power.
  • Aluminum 13° Latemodel Heads
    This Head is used in wide variety of racing.  Its a powerhouse that has great driveability.  The intake runner is quite a bit bigger than our 13 MOD head, which allows it to make more peak power and to run up higher in the powerband.  We use these heads in steel block and open latemodel racing as well as NE MODS on 415 to 434 Cubic Inch Engines.
