When it comes to maximizing the performance of your LS swapped Chevy, one of the most effective upgrades you can make is to replace your stock head gaskets with MLS (Multi-Layer Steel) head gaskets. This relatively inexpensive upgrade can unlock an additional 20-25 horsepower for around $200. In this article, we will explore the benefits of MLS head gaskets, how they work, and what you need to consider when upgrading.
Understanding MLS Head Gaskets
MLS head gaskets are designed to provide a superior seal compared to traditional composite gaskets. They consist of multiple layers of steel, which allows them to withstand higher levels of pressure and temperature. This makes them an excellent choice for performance applications, especially in LS swapped vehicles where power and reliability are crucial.
How MLS Head Gaskets Work
The construction of MLS head gaskets typically includes three layers: a top and bottom layer of steel with a middle layer that may be made of a softer material. This design allows the gasket to compress evenly and form a tight seal against the cylinder head and engine block. The enhanced sealing capability reduces the risk of blowouts and improves overall engine performance.
Benefits of Upgrading to MLS Head Gaskets
Upgrading to MLS head gaskets offers several advantages for LS swapped Chevys. Here are some key benefits:
- Increased Durability: MLS gaskets can handle higher boost levels and extreme conditions, making them ideal for performance builds.
- Better Sealing: The multi-layer design provides a tighter seal, reducing the chance of leaks and improving combustion efficiency.
- Improved Performance: By enhancing the sealing capability, you can unlock additional horsepower and torque.
- Cost-Effective: At around $200, MLS head gaskets are a budget-friendly upgrade that can significantly improve performance.
Installation Process
Installing MLS head gaskets requires some mechanical knowledge and tools. Here’s a general overview of the installation process:
- Preparation: Ensure the engine is cool and disconnect the battery. Remove any components obstructing access to the cylinder heads.
- Remove the Cylinder Heads: Carefully unbolt the cylinder heads and lift them off the engine block.
- Clean Surfaces: Thoroughly clean the mating surfaces of the engine block and cylinder heads to remove old gasket material and debris.
- Install MLS Gaskets: Place the MLS gaskets onto the engine block, ensuring they are aligned correctly.
- Reinstall Cylinder Heads: Carefully position the cylinder heads back onto the engine block and torque them to the manufacturer’s specifications.
- Reassemble Components: Reinstall any components that were removed and reconnect the battery.
Tools Required
- Torque wrench
- Socket set
- Gasket scraper
- Cleaning solvent
- Engine assembly lubricant
Considerations Before Upgrading
Before making the switch to MLS head gaskets, there are a few considerations to keep in mind:
- Engine Condition: Ensure your engine is in good condition. MLS gaskets require a smooth and flat surface for optimal sealing.
- Compression Ratio: If you have a high compression engine, consider using thicker MLS gaskets to avoid detonation.
- Supporting Modifications: Pairing MLS gaskets with other performance upgrades, such as headers and a tune, can maximize the benefits.
Conclusion
Upgrading to MLS head gaskets is a smart move for anyone looking to enhance the performance of their LS swapped Chevy. With the potential to unlock an additional 20-25 horsepower for a relatively low cost, this upgrade offers significant value. By understanding the benefits, installation process, and considerations, you can make an informed decision that will help you get the most out of your engine.
