Valve Covers for Your Small Block Chevy: A Buyer’s Guide
Picking the right valve covers for your small block Chevrolet engine is important. Valve covers protect your engine’s valvetrain and also give your engine bay a clean look. This guide will help you choose the best ones.
Key Features to Look For
When you’re shopping for valve covers, keep these important features in mind:
- Fitment: Make sure the valve covers fit your specific small block Chevy engine. Engines like the 350, 327, and 283 all have slightly different needs. Check the product description carefully.
- Height: Valve covers come in different heights. Standard height covers are common. Tall or extra-tall covers are needed if you have roller rockers or other valvetrain upgrades that take up more space.
- Baffling: Look for valve covers with oil baffling. Baffles help stop oil from splashing onto the rocker arms. This keeps oil where it needs to be and prevents oil from being sucked into the intake.
- Gasket Style: Valve covers use either a rubber or cork gasket. Some come with built-in gaskets. Think about which type you prefer.
- Mounting Holes: Most small block Chevys use six bolts per valve cover. Always double-check this.
Important Materials
The material of your valve covers affects their look, durability, and price.
- Steel: Steel valve covers are often the most affordable. They can be painted or chrome plated for a nice finish. Steel is strong but can rust if not cared for properly.
- Aluminum: Aluminum valve covers are lighter than steel ones. They don’t rust. Aluminum also dissipates heat well, which can be a small benefit to engine cooling. They often have a polished or brushed finish.
- Plastic/Composite: Some modern valve covers are made from strong plastics. These are very lightweight and won’t corrode. They are often used in newer vehicles but can be found for classic engines too.
Factors That Improve or Reduce Quality
A few things can make valve covers better or worse:
- Stamping vs. Billet: Valve covers that are stamped from a single sheet of metal are common. Billet valve covers are machined from a solid block of metal. Billet covers are usually more expensive but offer a very precise fit and a premium look.
- Finish Quality: A good finish means the paint, chrome, or polish is smooth and even. Poor finishing can lead to flaking paint or uneven chrome.
- Gasket Surface: The edge of the valve cover where the gasket sits must be flat and smooth. A warped or rough surface can cause oil leaks.
- Reinforcement: Some valve covers have extra metal reinforcement around the bolt holes. This stops the metal from bending when you tighten the bolts.
User Experience and Use Cases
People choose different valve covers for different reasons:
- Stock Replacement: If you just need to replace a damaged or old valve cover, a standard height steel or aluminum cover is a good choice.
- Performance Upgrades: If you’ve upgraded your valvetrain with roller rockers or a different camshaft, you’ll likely need taller valve covers to give everything enough clearance. Aluminum covers are popular for performance builds because they look good and are light.
- Show Cars: For show cars, appearance is key. Polished aluminum or chrome-plated steel valve covers can really make the engine bay stand out. Billet covers offer a custom, high-end look.
- Daily Drivers: For everyday use, durability and leak-free performance are most important. A good quality aluminum or steel cover with a proper gasket will serve you well.
Frequently Asked Questions (FAQ)
Q: What is the main purpose of valve covers?
A: Valve covers protect the valvetrain, like the rocker arms and springs, from dirt and debris. They also help contain engine oil.
Q: Do I need tall valve covers for my small block Chevy?
A: You need tall valve covers if you have upgraded parts like roller rockers or a high-rise intake manifold that take up more space under the stock covers.
Q: Can I use different brands of valve covers on my engine?
A: Yes, as long as they are designed for your specific small block Chevy engine model (e.g., 350, 327).
Q: What is the difference between steel and aluminum valve covers?
A: Steel covers are usually cheaper and heavier but can rust. Aluminum covers are lighter, won’t rust, and dissipate heat better.
Q: What does “baffled” mean for valve covers?
A: Baffled valve covers have internal shields to prevent oil from splashing onto the rocker arms and being forced into the PCV system.
Q: How often should I replace valve cover gaskets?
A: It’s a good idea to replace valve cover gaskets whenever you remove the valve covers, or if you notice any oil leaks.
Q: Will valve covers affect engine performance?
A: Not directly. However, ensuring proper fit and baffling can help your engine run smoothly by keeping oil where it belongs.
Q: Can I paint my steel valve covers?
A: Yes, you can paint steel valve covers. Make sure to clean and prime them properly before painting for the best results.
Q: What is a “billet” valve cover?
A: Billet valve covers are machined from a solid block of metal, offering a very precise fit and a high-end appearance, but they are typically more expensive.
Q: Are there any special tools needed to install valve covers?
A: You will need basic hand tools like a socket set and a torque wrench to properly install valve covers. A gasket scraper might be needed to clean old gasket material.
