If you're diving into the world of high-performance engines, you need a head gasket that can keep up. The COMETIC MLS (Multi-Layer Steel) Head Gasket is built for serious business. I’ve used these gaskets on my own rides, and I can tell you, they deliver a sealing performance that’s hard to beat—no need for extra sealants, which is a huge plus when you’re trying to keep things simple.

These MLS gaskets are incredibly versatile, perfect for setups with aluminum heads on aluminum blocks or even aluminum heads on cast iron blocks. They’ve got the strength to handle the shearing forces that come from the different materials without breaking a sweat. Made from multiple layers of stainless steel, they not only hold up under pressure but also bounce back when things get heated. And trust me, they can take the heat—thanks to the Viton coating on the outer layers, which is heat resistant up to a whopping 482°F (250°C). That’s essential when you’re pushing your engine to its limits.

The center layer is uncoated stainless steel, allowing for some flexibility in thickness. For this specific gasket, you're looking at a 3.86" bore diameter and a compressed thickness of just .030". That’s ideal for Buick’s V6 engines, especially if you’re running Stock or Stage I-II heads. It fits a range of models, from the Buick Century to the Cadillac Eldorado, and even some Chevy and Pontiac options. So, whether you're cruising in a classic or hitting the track, this gasket has you covered.
