Well I finally got the courage to tear my engine appart to replace the
head gaskets.  I found the Permatex Anaerobic Gasket maker #51813 that Ben
mentiones above but the instructions says to prepare the surface with a
gasket primer that comes in an aerosol.  Do people use that primer of do
you just clean the parts well and apply the 51813.  Thanks
