The Edelbrock Performer RPM CNC 87cc Bare Cylinder Head is a top-tier component designed for 1962-1979 Pontiac D-Port engines. This high-performance cylinder head is crafted with precision, offering an exceptional fit for 389, 400, 421, 428, and 455 V8 engines with a 4.060" or larger bore. With its D-Port exhaust port configuration, it seamlessly integrates with standard D-port exhaust systems, providing a seamless and efficient exhaust flow. The head's optimized oil return passages enhance oil flow, ensuring that your engine remains well-lubricated and running smoothly.

Key Features and Specifications

This cylinder head boasts an array of features that make it a standout choice for enthusiasts and professionals alike. Crafted from durable aluminum, it offers a lightweight yet robust construction. The head is designed to deliver up to 400-500 horsepower, thanks to its optimized intake runner volume of 204 cc and a push rod diameter of 0.312 in. The seat angle is set at 45 degrees for both exhaust and intake, ensuring optimal combustion and performance. The compact port size and extra thick port walls make it ideal for CNC and hand porting, allowing for maximum customization and performance potential. Additionally, the head includes guide plates, rocker studs, and a high-quality valvetrain for a direct bolt-on application, simplifying installation and enhancing overall efficiency.

Installation and Compatibility

The Edelbrock #61569 Performer Pontiac Bare Cylinder Head is designed for easy installation and compatibility. While the head comes with pre-installed valve guides and seats, it requires final sizing and a valve job to match the valves you plan to use. It's important to note that 350 C.I.D. engines may require notching the block for valve clearance. For those installing these heads, the three head bolt bosses are raised higher than standard D-port heights, necessitating the use of head bolt kit #8561. With these considerations in mind, the Edelbrock Performer RPM CNC 87cc Bare Cylinder Head is a reliable and efficient upgrade for your Pontiac D-Port engine, offering unparalleled performance and durability.
