Pro 1 SBC 180 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.

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Autoplicity had the best price for what I needed. I received my order within 2 days boxed up nice and tight. What more could you ask for? I will be a repeat customer.

Great site.  Provided needed technical specs.  Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.
