Multi Layer Stainless Exhaust Gasket That Seals Chrysler HEMI Headers with Precision
The SS-755872 is a multi layer stainless exhaust header gasket designed for Chrysler HEMI engines in 5.7L, 6.1L, 6.2L, and 6.4L displacements, featuring a D shaped port configuration that matches the HEMI cylinder head exhaust port geometry exactly. Multi layer steel gaskets provide superior sealing performance compared to single layer stamped gaskets in high performance header applications because the multiple steel layers create a controlled compression and recovery behavior across heat cycles, maintaining clamping force and a reliable seal even as headers and cylinder heads expand and contract with temperature changes.
The D shaped port opening of the SS-755872 matches the HEMI head directly without requiring port matching or trimming, and the stainless steel construction withstands the temperatures present at the cylinder head to header flange interface without burning out, compressing permanently, or cracking under the pressure cycles that terminate the service life of lesser gasket materials. Whether you are installing Kooks HEMI headers for the first time or replacing gaskets on an existing set during a rebuild, this gasket provides the correct multi layer stainless sealing solution for the Chrysler HEMI D port application.

Frequently Asked Questions
What engines does this gasket fit?
This gasket is designed for Chrysler HEMI engines in 5.7L, 6.1L, 6.2L, and 6.4L displacements using the D shaped exhaust port configuration. This covers a wide range of Dodge, Chrysler, and Jeep HEMI V8 applications.
What does multi layer stainless mean for a gasket?
Multi layer stainless, abbreviated MLS, refers to a gasket construction where multiple thin stainless steel layers are bonded together. The outer layers typically have a compliant coating for sealing, while the core layers provide spring back to maintain clamping load. This construction outlasts single layer stamped gaskets in high heat header applications.
Why is the port shape described as D port?
The HEMI cylinder head exhaust port opening has a D shaped cross section. This gasket gasket opening matches this shape to provide full port coverage without restricting flow or creating a mismatched sealing area.
Can this gasket be reused after removing headers?
MLS gaskets are designed for single use. The compression of the gasket layers during initial installation and heat cycling permanently sets the gasket. Replace with a new this gasket whenever the header is removed and reinstalled.
Do I need to use a sealant with this gasket?
No. Multi layer stainless gaskets are designed to seal without additional sealant. Using gasket sealer on an MLS gasket can actually impair its sealing function by preventing the layers from compressing and conforming properly.
Is this gasket compatible with the 6.2L Hellcat HEMI?
Yes. This gasket covers the 6.2L displacement HEMI variant. The Hellcat uses the same D port exhaust port geometry as other HEMI variants in this range.
What torque should I use with this gasket?
Use the header bolt torque specification provided in your Kooks header installation instructions. Correct torque is critical for MLS gaskets to compress and seal properly.
Will this gasket work with headers from other manufacturers?
Yes, in most cases. This gasket provides the correct port shape and bolt hole pattern for the HEMI D port head. As long as the aftermarket header uses the same flange bolt pattern, the gasket will fit.
How many gaskets are included in the set?
This gasket includes the gaskets required for the applicable HEMI application. Contact us to confirm the exact quantity for your specific installation.
What happens if I use a low quality gasket with performance headers?
Low quality or incorrect gaskets can blow out under the higher clamping pressures and temperatures of a performance exhaust installation, causing exhaust leaks that damage surrounding wiring, degrade performance, and create unpleasant odors and noise in the cabin.
Installation Instructions
- Ensure the HEMI cylinder head exhaust port surface is clean and flat before installing this gasket gasket. Remove any old gasket material thoroughly.
- Do not use gasket sealer with multi layer stainless gaskets.
- Position each this gasket gasket over the exhaust port with the correct orientation, confirming the D shaped port opening aligns with the cylinder head port and the bolt holes register correctly.
- Bring the header flange to the cylinder head, threading all header bolts by hand before applying torque.
- Torque header bolts in a crossing pattern, starting from the center bolts and working outward, to the specification in the Kooks header installation instructions.
- Re torque after the first heat cycle to account for initial gasket seating.
