Fel-Pro 1134 SD-4 Severe Duty Engine Cylinder Head Gasket

This is the Fel-Pro 1134 SD-4 Severe Duty engine cylinder head gasket, specifically made for Ford V8 Small Block engines like the 260, 289, 302 (excluding Boss engines), and 351W. When you're dealing with engines that see a lot of use, especially those with aluminum heads on cast iron blocks, you get scrubbing and movement that can make sealing tough. This gasket is built to handle those challenging conditions and keep a reliable seal.

Fel-Pro designed these performance head gaskets to manage the high cylinder pressures and head movement common in performance applications. They use strategically placed sealing beads around the combustion chambers and coolant passages. These beads concentrate the clamping force right where it's needed, which helps prevent leaks even under stress. The PermaTorque MLS (multi-layer steel) construction is their latest technology for these types of gaskets, offering a strong and durable sealing solution for demanding engine builds.

Keep in mind that this gasket is not intended for use in emission-controlled vehicles. If you're rebuilding a performance-oriented Ford V8, this gasket is a well-built option to ensure a solid seal.
