Dart 16374146 Cylinder Heads

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

320 Race Series BBC Cylinder Head
Full Port Assembly

Dart big block heads deliver superior performance without the hassles of welding and modifying stock castings. We applied proven Pro Stock technology to produce big block heads that out perform the competition yet Dart heads can be used with most off the shelf pistons, manifolds, headers and valve train components.

Features:

  • Premium alloy: Dart aluminum heads are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.
  • Shallow combustion chamber design improves combustion and allows use of larger valves for improved airflow.
  • Interlocking ductile iron valve seats are compatible with stainless steel and titanium valves.
  • Spark plugs are shifted toward bore centerline to enhance flame travel and reduce spark advance requirement.
  • Refined intake port design reduces turbulence and increases air/fuel flow.
  • Optional spread exhaust ports allow use of larger primary tubes without header plates.
  • Water passages between exhaust ports improve cooling and prevent hot spots that can cause head gasket failure.
  • Gasketed 3/4 reach spark plugs offer widest selection of heat ranges.
  • All cylinder heads sold individually.

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Fantastic service and fast shipping! Lowest price on the net for the CAI that I bought!<br><br>This is my new "Go To" website for parts.<br><br>Thanks!

I would def order again from them great price and fast shipping.

Wow the quick service and low prices at autoplicity helped me and made it easy to find which car parts retailer is the best!

Website easy to navigate...best pricing i've found.

Great price, fast shipping, excellent customer service. I will definitely do business with them in the future.

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.

Autoplicity had the best price on the Wiseco pistons I needed anywhere. Took a little longer to arrive than I expected but apparently that was due to the pistons being shipped directly from the factory. Otherwise a very good experience overall.
