Choosing the Best Heads for Your 350 SBC: A Buyer’s Guide
So, you’re looking to upgrade your trusty 350 Small Block Chevy (SBC)? That’s a great move! Cylinder heads are like the lungs of your engine. They control how much air and fuel get in and how fast the exhaust goes out. Getting the right heads can make a huge difference in how your engine runs, whether you want more power, better fuel economy, or just a smoother idle. This guide will help you pick the perfect heads for your 350 SBC.
What to Look For in 350 SBC Heads
When you shop for heads, a few things stand out.
1. Key Features to Look For
- Combustion Chamber Size: This is measured in cubic centimeters (cc). Smaller chambers make more power with less displacement, but they can also raise the compression ratio. Bigger chambers lower compression. For a street-driven 350, heads with chambers around 64cc to 76cc are often a good starting point.
- Intake and Exhaust Port Size: Bigger ports let more air and fuel in and exhaust out. For a street engine, you don’t want ports that are too big, or you might lose velocity, which hurts low-end torque. For a race car, bigger is usually better.
- Valve Size: Larger valves let more air and fuel in. For most street 350s, intake valves around 1.94 inches and exhaust valves around 1.50 inches are common. High-performance builds might use larger valves.
- Bolt Pattern: Make sure the heads match your intake manifold. Most SBC heads use standard bolt patterns.
- Spark Plug Angle: Some heads have straight spark plug holes, while others have angled ones. This can affect header clearance.
- Guide Material: The valve guides keep the valves moving straight. Bronze or manganese bronze guides are good for performance.
2. Important Materials
- Aluminum: These are lighter and dissipate heat better than iron. They can also improve performance because they allow for better airflow. However, they cost more.
- Cast Iron: These are heavier but more affordable. They are also very durable. Many stock engines come with cast iron heads.
3. Factors That Improve or Reduce Quality
- Casting Quality: Smooth ports and chambers with no rough spots or imperfections are a sign of good quality. This helps air flow better.
- Valve Job: A good valve job means the valves seal perfectly against the valve seats. This is crucial for performance and efficiency.
- Porting and Polishing: Some aftermarket heads come with ports that are already smoothed and shaped for better airflow. This adds to the cost but improves performance.
- Assembly: Heads that come fully assembled with valves, springs, and retainers are convenient. Make sure the components are good quality.
4. User Experience and Use Cases
- Street Performance: If you drive your car daily or on weekends, you want heads that offer a good balance of power and drivability. Heads with moderate port sizes and good airflow will give you a noticeable power boost without sacrificing low-end torque.
- Drag Racing/Track Use: For these applications, you’ll likely want larger ports, bigger valves, and higher compression ratios. These heads are designed for maximum airflow and power at higher RPMs.
- Restoration: If you’re restoring a classic, you might want to stick with stock-style heads or reproduction heads that look the part.
- Budget Builds: Cast iron heads are a great option for budget-conscious builders. You can often find good used ones or affordable new aftermarket options.
Frequently Asked Questions (FAQ) About 350 SBC Heads
Q: What are the main Key Features I should look for?
A: You should look for the combustion chamber size, intake and exhaust port size, valve size, and bolt pattern.
Q: Which material is better, aluminum or cast iron?
A: Aluminum heads are lighter and improve performance, but they cost more. Cast iron heads are cheaper and durable.
Q: How does combustion chamber size affect my engine?
A: Smaller chambers increase compression and power. Larger chambers lower compression.
Q: What valve size is good for a street 350?
A: Intake valves around 1.94 inches and exhaust valves around 1.50 inches are a good start for most street engines.
Q: Should I buy assembled heads or bare heads?
A: Assembled heads come with valves and springs, which saves you time. Bare heads let you choose your own components.
Q: What does “porting and polishing” mean for cylinder heads?
A: It means smoothing and shaping the intake and exhaust ports to help air flow better.
Q: Will new heads make my engine sound different?
A: They can. Better airflow can sometimes lead to a slightly more aggressive exhaust note.
Q: How much power can I expect to gain from new heads?
A: Gains can range from 20 to 70 horsepower or even more, depending on the heads and the rest of your engine setup.
Q: Do I need to change my camshaft if I change my heads?
A: Often, yes. A camshaft designed to work with your new heads will give you the best results.
Q: Where can I find good quality 350 SBC heads?
A: Reputable automotive parts stores, online retailers specializing in performance parts, and engine building shops are good places to look.
