Cometic 68+ Volvo B20A/E/F 90mm .030 inch MLS Head Gasket

What you get here is a Cometic Multi-Layer Steel (MLS) head gasket, specifically sized for a 90mm bore and with a compressed thickness of .030 inches. This gasket is built for a range of Volvo B18 and B20 engines found in models like the 122, 142, and 1800, covering many years from the early 60s through the mid-70s.

This isn't just any gasket; it's made from multiple layers of stainless steel, which gives it a lot of strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs up to 482 degrees Fahrenheit. This construction means it seals really well on its own, without needing any extra sealants, and it works great whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The stainless steel layers can also handle the different expansion rates between those materials.
