Very good gaskets. Not the gaskets fault you have to remove everything but the fuel tank to r & r the valve covers. VERY easy to snag gasket on clutter when installing. Here was my trick. Put NARROW bead of good silicone in valve cover groove all the way around. Firmly seat gasket in valve cover groove . Place valve covers face down on flat , clean surface 3 feet apart. Put 2 wooden 4x4 s across top of valve covers. Use engine hoist to set ass end of L120 John Deere lawn mower on planks to apply even pressure and leave over night. Sounds redneck but those gaskets stick so tight you never have to worry about snagging them when installing.! (Posted on 5/17/2019)
