Fel-Pro 1134 SD-5 Severe Duty Engine Cylinder Head Gasket

If you're rebuilding the top end of a Ford V8 Small Block engine, like the 260, 289, 302 (excluding Boss engines), or 351W, a solid head gasket is crucial for sealing. This Fel-Pro 1134 SD-5 gasket is built for those tougher jobs where engines might see extra scrubbing and movement, especially when you have different metals like aluminum heads on a cast iron block.

Fel-Pro designed these gaskets to handle the higher cylinder pressures and movement that can happen in performance-oriented engines. They use strategically placed sealing beads around the combustion chambers and coolant passages. This concentrates the clamping force right where it's needed most, helping to prevent leaks. This particular gasket uses a multi-layer steel (MLS) construction, which is a well-known approach for robust sealing in demanding situations.

Keep in mind that this gasket is not intended for use in vehicles with emissions control systems. Always refer to manufacturer instructions for proper installation procedures.
