Cometic Gasket MLX Head Gasket

7.0L Drag Pak Engine

Part #: C15391-072

Overview

The Cometic MLX Head Gasket with a 4.200" bore and .072" thickness is engineered specifically for the 7.0L Drag Pak engine. Designed to deliver superior sealing performance, this gasket utilizes advanced HP shim technology to enhance clampload around the combustion chamber. This results in improved sealability, especially important for high-performance and drag racing applications where engine durability and reliability under extreme conditions are critical.

Ideal for racers and performance enthusiasts running the 7.0L Drag Pak, this head gasket ensures consistent compression and prevents leaks, helping maintain optimal engine performance during demanding runs.

Key Features

The Cometic MLX Head Gasket incorporates several advanced features to meet the rigorous demands of drag racing engines:

• HP shim technology increases clampload around the combustion chamber for enhanced sealing
• Precision 4.200" bore size tailored for the 7.0L Drag Pak engine
• .072" thickness balances durability with proper gasket crush for reliable sealing
• Multi-layer steel (MLS) construction for strength and heat resistance
• Designed to withstand high cylinder pressures and extreme thermal cycling
• Compatible with open deck block designs, improving gasket-to-block interface
• Manufactured by Cometic Gasket, a trusted name in high-performance sealing solutions

Construction & Design

The MLX head gasket features a multi-layer steel (MLS) design, combining multiple thin layers of high-grade steel with elastomer coatings to provide a durable, flexible seal. The HP shim technology integrated into the gasket enhances the clampload around the combustion chamber, which is critical for maintaining a tight seal under the high pressures generated by the 7.0L Drag Pak engine.

This gasket is engineered to accommodate the open deck block architecture of the Drag Pak, ensuring optimal contact and sealing performance. The .072" thickness is carefully selected to provide the right balance between gasket crush and durability, preventing blowouts and leaks during high-stress operation.

Installation & Fitment

The Cometic MLX Head Gasket is designed for direct fitment on the 7.0L Drag Pak engine, requiring no modifications for proper installation. It is essential to follow manufacturer torque specifications and installation procedures to ensure maximum sealing performance and longevity. Proper surface preparation and clean mating surfaces are critical to achieving the best results with this gasket.
