installed correctly the raised bead around each port increases the pressure
exerted on the gasket directly adjacent to the port and effectively prevents
leaking gaskets. It is important when installing the header, to install all
bolts loosely, then tighten evenly to ensure the flat installation of the
flange. It is normal for the flange to be raised off the cylinder head the

barely touch. Second, using the same inside-out pattern, tighten each bolt
until finished. This method will help prevent leakage and will give the user
