Review on GM Genuine Parts 89060413 Intake Manifold Gasket Kit: Ensuring Reliable Performance with Side Intake Gaskets by Corey Michaels

Really very easy to install. Since they snap into place, you don't have to worry about them moving with the inlets on the heads. They're a little more expensive than Felpro (which is also a quality product) but for the time it took to get the job done I didn't want to worry about having to do it all over again due to issues with gaskets coming out during alignment Installation.
