Small-block Chevy (SBC) engines remain one of the most popular performance engine platforms in the automotive world. Their versatility, affordability, and massive aftermarket support make them a favorite for everything from street machines to dedicated drag racing builds. If you’re looking for an airflow upgrade for your SBC project, the Power Products CNC-ported aluminum cylinder heads available through Competition Products are worth a closer look.
These Power Products cylinder heads were designed to deliver excellent airflow while maintaining street-friendly drivability. They are ideally suited for small-block Chevy engines in the 383- to 421-cubic-inch range and offer a strong balance of low-end performance and top-end horsepower.
With 210cc intake runners, impressive intake and exhaust flow numbers, and compatibility with both naturally aspirated and boosted combinations, these cylinder heads are a strong choice for a wide range of high-performance street and street/strip applications.
Why The 210cc Intake Runner Size Matters
According to Brian Adix of Competition Products, the decision to use a 210cc intake runner was intentional.
“The 210cc intake runner volume isn’t huge by modern standards, which is intentional,” Adix explains. “It allows the head to work well on typical small-block combinations without sacrificing velocity and responsiveness. It offers a good balance between low-end performance and top-end airflow. It’s especially well suited for traditional small-block combinations rather than very large-displacement small-blocks.”
That combination of airflow and velocity makes these heads particularly attractive for enthusiasts building 383 stroker engines, 406 combinations, and other popular street-oriented SBC setups.
CNC-Ported Airflow And Premium Features
Competition Products lists the Power Products CNC-ported aluminum cylinder heads at 300 cfm of intake airflow, while the exhaust ports flow up to 239 cfm. Those numbers provide the airflow needed to support serious horsepower without sacrificing drivability.
Additional features include:
- CNC-ported intake and exhaust runners
- Bronze valve guides
- Hardened valve seats
- Large spring seats
- Multi-angle valve job
- Compatibility with naturally aspirated and boosted applications
The cylinder heads are available either bare or fully assembled and ready to install, giving engine builders flexibility based on their project requirements.
A Strong Upgrade For Street And Strip SBC Builds
Whether you’re building a 383 stroker, a 421-cubic-inch small-block Chevy, or another high-performance SBC combination, these CNC-ported aluminum cylinder heads offer a proven balance of airflow, velocity, and durability. Their street-friendly design and strong flow characteristics make them an excellent option for enthusiasts looking to maximize performance without sacrificing responsiveness.
