HEADER TIP : Before changing header gaskets, you should ensure your header flanges are straight. If they are not straight or flat, they will leak. A file can be used to get minor warps flattened. If you have bent bolt hole flanges, those will also need to be repaired or the flange will bottom out on the cylinder head before the gasket is properly compressed, causing the gasket not to seal properly. Always use quality bolts and properly torque them to ensure leak-free repairs.
