Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Frustratingly fun!
Format: Paperback
Delightfully frustrating looking through pages and pages of names but it’s quite fun if you have the patience. I bought it to keep me entertained while waiting for my broken leg to heal. I was determined to find it! Looking forward to doing another one.

Pages falling out of binding.
Format: Paperback
I love the book. It’s been fun. My issue is the pages are falling out. I received the book today and every other page comes right out of the binding. I am worried I am going to lose pages.

Great mystery concept, poor paper quality
Format: Paperback
Love the concept and the book but the quality of the paper and cover just really disappoints me. Because you have to flip back and forth you’re going to be handling this a lot. I had the book at the pool and the edge got wet and the cover just delaminated and came apart. I have really enjoyed the complexity of this mystery and cannot wait to find out who the killer is!

Perfect for Mystery Lovers and Overthinkers
Format: Paperback, Format: Paperback
I picked this up thinking it would be a quick little puzzle book and ended up way more invested than I expected. The entire concept is basically solving a murder mystery through elimination clues, and it honestly feels like a mix between Clue, logic puzzles, and a detective game you can do by yourself. Each page gives you clues about who the killer is NOT, so you slowly narrow down the suspects by crossing out names based on things like syllables, vowels, letters in their name, etc. Some clues are super straightforward and others make you stop and really think. It’s surprisingly addicting once you get into it. What I like most is that it actually keeps your brain busy for a long time. This is not one of those puzzle books you finish in an hour and forget about. I’ve been working through it slowly because there are SO many pages and clues. It’s honestly kind of funny how serious I got trying to figure it out. The layout is easy to follow, the concept is original, and it’s a great option if you like mystery games, logic puzzles, escape rooms, or anything detective-related. I could also see this being really fun to bring on a trip or keep around for downtime instead of scrolling on your phone. Definitely worth it if you enjoy interactive mystery books and want something different from the usual word searches or crossword puzzles.
