Product Details
Dart 18300000 Cylinder Heads
Big Chief 14 Degree Cylinder Head
Bare Casting

The Big Chief head has dominated in sportsman classes since its introduction, and we have continued to improve the design with the latest Pro Stock Technology. With our sophisticated CNC machining programs, we can tailor a pair of Big Chief heads to fit your exact engine combination.

It is recommended that you contact a Dart technical representative before placing an order for this item. Detailed information about your planned engine build will help to ensure that you choose the right configuration for your motor and that any special parts and considerations are taken into account.

Features:

  • Premium alloy: Dart aluminum heads are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.
  • 18 rolled valve angle and raised ports for excellent air/fuel flow characteristics.
  • 5-axis CNC machined intake and exhaust ports and combustion chambers.
  • Huge 2.400 intake and 1.900 exhaust valves.
  • Stainless steel or titanium valves available.
  • Spread port design eliminates inefficient port locations, increasing power and consistency.
  • Raised spark plug location improves flame travel for a quicker, more complete burn, producing more power.
  • All cylinder heads sold individually.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.
