DESCRIPTION

Dart's long awaited 6-bolt LS3 heads have arrived! We here at Borowski Race Engines received the first set shipped, paired the heads with a Dart LS Next block and added nitrous. Engine Labs online magazine ran the story as a tech feature http://www.enginelabs.com/engine-tech/cylinder-heads/tech-a-deep-dive-into-the-all-new-pro1-ls3-head-from-dart/

Quoting the article": "By creating a cylinder head casting that performs like a ported design right out of the box, Dart has developed a serious advantage—especially when you take the price point of these cylinder heads into account, which Maskin says will hit the marketplace approximately $200 less per head than competing designs, while offering better performance."

Details
Dart's all-new Pro1 LS3 cylinder head features the latest in port and combustion chamber design. The company's investment in casting and tooling capabilities allows them to produce a cylinder head design that is unrivaled in the market.

Assembled cylinder heads are available with 1.290-inch beehive or 1.295-inch dual valve springs to suit nearly any application. The valve seats feature a five-angle design for the intake valve and a three-angle design for the exhaust valves to promote excellent flow.

Cylinder heads work on LS and LS Next-style blocks with a four or six-bolt configuration for maximum clamping ability.
Racing inspired combustion chamber improves flame propagation and increases air flow.

Dart has designed these as-cast cylinder heads to perform like ported cylinder heads--maximizing performance and minimizing your investment.

Internal Borowski testing with these cylinder heads prove they are capable of well over 1,000 horsepower and 1,000 pound feet of torque.
