What is the recommended compression ratio with these heads?

The 64cc combustion chambers on these heads are ideal for achieving approximately 12.5:1 compression when used with a 12cc domed piston in a 350 V8 engine. This compression level is suitable for high-performance street and competition use.

Are these heads compatible with hydraulic roller camshafts?

No, these Edelbrock Victor Jr. cylinder heads are specifically designed to work with mechanical roller camshafts. They come with springs that are matched for this type of valvetrain.

What other components are typically needed to install these cylinder heads?

Beyond the cylinder heads themselves, you will need appropriate gaskets for the intake manifold and exhaust, head bolts or studs, and a compatible mechanical roller camshaft and valvetrain. Refer to the manufacturer's installation instructions for a complete list of recommended components.

About this part

Product Details

What you get with Edelbrock part #77599 is a pair of Victor Jr. 23-degree cylinder heads specifically built for Small Block Chevy 262-400 V8 engines that use a mechanical roller camshaft. These heads are engineered to unlock maximum power, making them a strong choice for both competition racing and high-performance street applications where every bit of power counts.

These heads feature 64cc combustion chambers, which are ideal for achieving around 12.5:1 compression when paired with a 12cc domed piston in a 350 V8. This setup is perfect for an entry-level race car or a serious street machine. They come equipped with springs ready to handle mechanical roller camshafts and accept standard 23-degree valvetrain hardware, simplifying your build. The angled spark plug holes are a thoughtful touch that can help with plug access and wire routing in tight engine bays.

With these heads, you can expect the potential for significant horsepower gains, with estimates suggesting 530-580 hp right out of the box. This makes them a cost-effective way to build a race-winning engine setup without breaking the bank. Keep in mind that these heads are not CARB approved and cannot be shipped to California.
