Dart Pro 1 CNC Ported, 360 BBC Cylinder Heads, Assembled

 PRICING IS PER PAIR   These are the same heads as we use in our Big Block builds like this one.  You therefore know that we like them and they work. Another big advantage is that we almost always have them in stock. We buy these Dart Pro 1 BBC cylinder heads as porter castings so that we can do the machining on our own CNCs.  The finished heads are therefore not the same as the Dart's.  The Dart machined heads are great, but ours flow even better and in our experience, make more horsepower. How do we get these results? Because we are not doing high volume production like Dart, we are constantly tweeking the port designs on the heads we run through our Rottler 5-axis CNC.  The net result is that the geometry of our finished cylinder heads is constantly evolving whereas an OE's design will be more static.  Another big advantage we have is our our Newen CNC seat & guide machine.  Check out the videos below to see these machines at work and the advantages the Newen brings to cylinde
