These are quality gaskets for the price. They say Trickflow, but they are in fact Felpro gaskets. Felpro has been making quality gaskets longer than I've been alive, and I trust their products. These are not oem gaskets. They fit perfect, but they are paper gaskets and not the o-ring style that comes from the factory. The only problem with paper gaskets is if you have to remove them again for any reason... You have to scrape off the gasket that's left behind. The other thing worth noting is that these gaskets do not have the oem registration marks. What this means is that you don't simply lay they gasket on the head where it lines up, and bolt your intake down because the gasket will move around while you're fitting the intake into place. I highly recommend using permatex 'high tack' when installing these. Simply apply the high tack to the mounting surface of the intake, place the gaskets on making sure to line all holes up, and allow it to sit for 10 minutes or so. The high tack will bind the gaskets to the intake and keep them firmly in place while you're fitting the intake back into position.
