    You have to remove rocker assy all six inj not really a bad job make sure to use a little silicone on the gasket and also make sure the rocker box is true this is a common leak when you put it back together make sure you adjust the clearence on the rocker shaft stands I can get you the info if need be.you will need rocker box gasket valve cover gasket and inj o rings make sure you check the injector harness where it plugs in on the outside of the rocker box.also check for coolant in the inj bores l10,m11,ism are common to have leaking coppers

    Your tearing everything down to the head. Probably looking at a good 8 hours or so.
