Product Details

Dart 11321111P Cylinder Heads



FULLY CNC PORTED.

Pro 1 SBC 200 Cylinder Head

The redesigned chamber features improved fuel distribution , spark plugs are located high and as close to the center of the chamber as possible and five angle intake seats shear the liquid fuel and air as it enters the chamber. The intake face, exhaust face and exhaust ports have been redesigned, valve guide bosses are profiled and casting walls are cleaner and more consistent, resulting in greater control over flow, heat and combustion. Multiple intake sizes are available to suit engines from mild street to big-inch full competition.

Features:

  • Premium alloy: Dart aluminum heads are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.
  • Bolt on compatibility: Standard valve angle and spacing are retained to allow use of off the shelf pistons and valve train components.
  • Heart shaped chambers improve combustion efficiency and fit most standard pistons.
  • Multi-angle intake seats and radiused exhaust seats dramatically increase airflow.
  • Hardened exhaust seats are compatible with unleaded gasoline.
  • Manganese bronze intake valve guides and phosphorous bronze exhaust valve guides extend cylinder head life.
  • Choice of angled or straight spark plugs to clear manifolds and headers.
  • Spark plug holes are machined for gasketed 3/4 reach plugs.
  • 5-axis CNC bowl blended for optimal flow characteristics.
  • Dual exhaust bolt pattern spot is provided for easy header fitment.
  • All cylinder heads sold individually.

Na

I would use them again

Good Experience!

Quick and easy.

Easy part search engine, easy order system and fast free delivery.

My idea of a perfect online shopping experience

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

This company offers profesional service at a very competitive price. The header collectors i ordered were not available at the big speed outlets. The fast shipping was also a plus. I would recomend Autoplicity to anyone who needs parts in a hurry !

Best price on the web. Very helpful customer service.

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

Very easy to order with PayPal!

Great exchange. Received product as described and in a timely manner. Thanks! Will Do business again

I am impressed with they mail order service. Recommended.
