  P5007708AB and P5007445AB must be used on a race block with 48° tappet bores and custom cam. P5249769 fits stock-style OE blocks with standard 59° tappet bores and standard cam.

For small-block Mopar enthusiasts looking to unlock serious airflow, torque, and durability, the Mopar Performance W2 Cast Iron Cylinder Heads give you everything you need. These heads are built for racers, street machines, and anyone who wants to push the limits with a strong foundation—without sacrificing real-world driveability.

The mopar w2 heads feature raised oval intake ports and are machined for 2.02-inch intake and 1.60-inch exhaust valves, setting the stage for excellent flow and strong top-end power, while retaining enough flexibility to still pull hard down low. The cast-iron construction offers outstanding strength and heat retention—ideal for drag strip launches, circle track punishment, or high-rpm abuse. Because they are sold individually and as bare heads (no valves, no springs), you have the freedom to choose components to match your exact build and budget.

Fitment varies depending on build choice: some versions are designed for race blocks with 48° tappet bores and custom camshafts, while others fit standard OE blocks with 59° tappet bores for easier installation. These heads require W2-style intake manifolds, race rocker arms, and headers suited to their relocated exhaust ports. Expect raised performance when you upgrade—all that hardware pays off in a smoother idle, stronger midrange, and power that keeps pulling through the rev band.

Why choose W2 heads now? With rising demand for reliable airflow and consistent performance in high-stress environments, these heads deliver proven race pedigree and tangible gains without the extreme cost of racing aluminum heads. If you’re ready to upgrade your valvetrain setup and aren’t afraid to match quality with the necessary supporting parts, these w2 heads are a smart, powerful investment. Add a set to your build and watch your small-block Mopar open up like never before.
