Dart Iron Eagle Meets the Cometic MLX Head Gasket

Thursday, September 18th, 2025

When it comes to pushing the Toyota 2JZ platform to its limits, every component matters. Whether you are building a stock 2JZ GE or GTE or stepping into Dart’s all new Iron Eagle block, head gasket integrity is the difference between reliability and failure. That is why Cometic engineered the 2JZ MLX Head Gasket, a solution designed from a clean slate that matches the strength of the Iron Eagle while maintaining compatibility with factory 2JZ blocks.

MLX Engineering for Maximum Boost

The MLX gasket is more than a seal, it is a system. Built to withstand extreme cylinder pressures, MLX uses multiple layers of stainless steel with a proprietary coating that resists combustion leakage and coolant migration. This allows racers and tuners to run higher boost levels with the confidence that sealing will not become a weak point.

Unlike conventional gaskets, the MLX design focuses on combustion chamber integrity, heat resistance, and load distribution across the head surface. That means improved reliability whether you are running high horsepower drag passes, extended time attack sessions, or aggressive street builds.

Fitment Options:

C14016 Series (M11x1.25 Studs): Fits stock 2JZ GE and GTE and Dart Iron Eagle

C14212 Series (1/2 inch Studs): Fits Dart Iron Eagle 2JZ with larger hardware

Bores and Thickness: 87mm bore, .052 inch or .062 inch thickness

Unlock the 2JZ Potential

The Toyota 2JZ has long been celebrated as one of the most durable inline six engines in motorsports history. But like any platform, it has its shortcomings under extreme load. Dart’s Iron Eagle 2JZ block was engineered to address those weaknesses by strengthening cylinder walls, improving cooling passages, and allowing larger hardware like 1/2 inch studs for clamping force.

Pairing this block with Cometic’s MLX gasket creates a synergy that eliminates sealing failures and ensures the block and head can handle immense power levels without compromise. From hot rodders and drifters to drag racers chasing four digit horsepower, this combination was designed for those who refuse to let sealing be their limitation.

Why It Matters

• Sealing Integrity: Prevents combustion leakage under extreme boost

• Durability: Stainless steel layers resist fatigue and distortion

• Compatibility: Works with both OEM Toyota 2JZ and Dart Iron Eagle

• Flexibility: Available in multiple stud configurations and thicknesses
