Dart 19000171 Cylinder Heads

2.100 X .502 X 11/32 MAG BRONZEBIG BLOCK INTAKE

Pro 1 BBC 275 Oval Port 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.

Easy check out I like the PayPal option

Unbeleively fast shipping. I ordered on a Tuesday night, and it was delivered to my door by Thursday. Plus, the item was the cheapest with shipping on the web! I will most certainly be doing business with them again!

good so far

Great selection and easy checkout! The only thing is I didnt get an email confirmation as soon as I order which made me wonder is the transaction went through. I did get an email once the items were shipped though.
