According to my experience, the Fel Pro MS 98007 Permadryplus Manifold gasket didn't live up to its promises. Despite its claims of being a high-performance gasket, it failed to provide a reliable seal and leaked after just a few uses. The pros of this gasket are its easy installation and compatibility with most automotive engines .However, the cons outweigh any benefits, making this gasket a poor choice for those seeking a reliable and durable solution for their automotive needs..
