Overview

Redesigned Dart Pro 1 chamber with improved fuel distribution. Spark plugs located high and close to chamber center. Five-angle intake seats shear liquid fuel and air. Redesigned intake face, exhaust face, and exhaust ports. Profiled valve guide bosses, cleaner and more consistent casting walls for greater flow, heat, and combustion control. Multiple intake sizes available for mild street to full competition engines. 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 retained for off-the-shelf pistons and valvetrain 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 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 machined for gasketed 3/4" reach plugs. Dual exhaust bolt pattern for easy header fitment. Sold individually.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
