These gaskets are the real deal! They fit perfectly and are very durable. I experienced no leaks and my engine has been running much smoother since replacing my old gaskets with these. The gaskets are made with high-quality materials, ensuring longevity and reliability. The only con I can think of is that they are a bit costly, but you get what you pay for .Overall, I highly recommend these gaskets for anyone looking to improve their automotive engine's performance..
