Intake Manifold Gasket Recommendations

Regardless of brand, many people leave out the front & rear end gaskets and just use silicone. Some end gaskets squeeze out and others are too thick or hard and don't let the intake sit low enough. Make sure the intake lines up properly with the side gaskets in place. Depending on any other machining, you may need to mill the intake a bit. You don't want to elongate the manifold bolt holes.
