Product Details

Dart 19100112 Cylinder Heads



FULLY CNC PORTED.

Pro 1 BBC 310 Cylinder Head

Every intake port, every exhaust port, every valve bowl and every combustion chamber is 100% CNC machined on special, dedicated Pro 1 castings. Our 5-axis computer controlled machining centers produce compound curves and complex shapes that no human could duplicate with a hand grinder.

Features:

  • Premium alloy: Dart aluminum heads are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.
  • Bolt on compatibility: 2 degree rolled valve angle and standard spacing accommodates all stock accessories.
  • Heart shaped 121cc chambers improve combustion efficiency.
  • CNC machining ensures that every chamber has the same volume so that every cylinder maintains equal compression.
  • Raised spark plug location improves flame travel for a quicker, more complete burn, producing more power.
  • Multi-angle intake seats and radiused exhaust seats greatly improve air flow.
  • Hardened exhaust seats are compatible with unleaded gasoline.
  • Exhaust ports raised .300 to improve flow (requires 1 longer head bolts next to exhaust ports).
  • Spark plug holes are machined for gasketed 3/4 reach plugs.
  • Manganese bronze valve guides ensure long term reliability.
  • All cylinder heads sold individually.

They had the lowest price on the web and carried the part I needed. They used amazon. Heck out so it was super easy to place the order and the part shipped right away. Will definitely order from again.

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

Fast and easy transaction.

This is a great e-retailer. Best price and fast shipping. I ordered a bike rack. Their price was the lowest I could find, and it was drop shipped from the manufacturer the following day, and arrived in time for me to use it on the weekend. The one criticism I would have is the item description could have been better. From my web research, I knew the model I wanted, but if I was just browsing bike racks on their website, I would have needed more information.

Great service. Quick shipping!

Best parts at the best price, will continue to order from Autoplicity. Shipping is also very fast.
