Description

Product Overview

Remflex has engineered the 2035 exhaust gasket to address the most common failure points in high‑performance V8 applications. The gasket features a D‑shaped port that matches the geometry of big‑block Chevrolet cylinder heads, providing a direct seal that eliminates the need for custom machining. Constructed from a high‑temperature resistant composite, the gasket maintains its integrity under extreme heat cycles, while its 1/8 inch thickness offers a balance of rigidity and compressibility. When installed, the material crushes up to 50 percent, allowing it to fill surface imperfections as deep as 1/16 inch, creating a leak‑free barrier between the head and the header. The product dimensions of 34.2 by 5 by 0.5 inches accommodate a wide range of header configurations, and the painted exterior protects against corrosion and oil exposure. With a lightweight design of just 5.6 ounces, the gasket is easy to handle during installation, reducing the risk of damage to surrounding components.

The 2035 model is listed under Remflex’s performance exhaust line and has earned a solid reputation among automotive enthusiasts for its reliability and ease of use. Customer reviews consistently rate the gasket at five stars, highlighting its ability to resolve persistent exhaust leaks that other products could not address. The universal fit designation means the gasket can be used in a variety of header and manifold setups, making it a versatile choice for both street and track applications. Its compatibility with aftermarket AFR Magnum cylinder heads further expands its appeal to those seeking to upgrade their engine breathing capabilities.

Usage

This gasket is ideal for any situation where the exhaust system experiences significant thermal expansion and contraction, such as high‑performance street builds, race‑ready engines, and heavy‑duty towing vehicles. Install the gasket when assembling a new header set, replacing a worn‑out gasket, or performing a complete exhaust overhaul. The product’s ability to conform to uneven flange surfaces makes it especially useful in older engines where metal fatigue may have caused warping. Technicians and DIY mechanics alike will appreciate the straightforward installation process: simply align the D‑shaped port with the corresponding head opening, apply a uniform torque to the header bolts, and allow the gasket to compress into place. The result is a durable seal that withstands the rigors of daily driving, aggressive acceleration, and prolonged high‑rpm operation.

Because the gasket is designed to work with both aluminum heads and steel headers, it accommodates the differing expansion rates of these materials. This reduces the likelihood of flange separation that can lead to exhaust leaks, reduced back‑pressure control, and potential engine damage. Whether the vehicle is a classic Chevrolet 396‑engine hot rod or a modern performance build, the Remflex 2035 gasket provides a reliable solution for maintaining optimal exhaust flow and engine efficiency.

FAQ

Can this gasket be used on aftermarket AFR Magnum heads?

Yes, the 2035 gasket is compatible with AFR Magnum cylinder heads. The D‑shaped port aligns with the head opening, providing a secure seal for both stock and aftermarket configurations.

What torque should be applied to the header bolts during installation?

We recommend tightening the header bolts in a criss‑cross pattern to the manufacturer’s specified torque, typically between 30 and 45 foot‑pounds. This ensures even compression of the gasket and prevents uneven stress on the flange.

Is the gasket suitable for high‑performance racing applications?

Absolutely. The gasket’s high‑temperature composite material and ability to fill surface imperfections make it ideal for race‑ready engines that experience rapid temperature changes and high exhaust pressures.

How does the warranty cover material defects?

The warranty covers any failure caused by material defects for a period of one year from the date of purchase. If the gasket fails under normal operating conditions, Remflex will replace it at no additional cost.

Can the gasket be reused if removed during a repair?

We advise against reusing the gasket after removal. The compression and sealing properties are designed for a single installation to ensure optimal performance and safety.
