4.100 MLS Head Gasket - .041 SBC LS1 RH

The 4.100 MLS Head Gasket - .041 SBC LS1 RH from FEL-PRO is designed for small-block Chevy and LS1 builders who require a reliable sealing solution for high-performance applications. This gasket is particularly suited for those building engines that combine LS1 aluminum heads with SBC blocks, ensuring compatibility and performance.

Constructed from multi-layer steel (MLS), this gasket utilizes advanced technology to maintain a consistent seal across varying surface finishes and operating temperatures. The .041-inch thickness is engineered to optimize compression ratios and combustion chamber volume, making it a vital component for engine builders targeting specific power outputs.

Engine builders will benefit from the precise alignment of head bolt holes with the cylinder head and block, which simplifies installation. The right-hand configuration aligns with OEM valve cover and accessory mounting layouts, making it easier to integrate into existing setups without the need for custom fabrication.
