Just asking here but you did use the alignment rings when you installed the intake exhaust manifolds correct? If it were me, I would probably unbolt the intake/exhaust, clean up the fuel leak marks on the block, little paint touch up if necessary, and reinstall using a Rimflex gasket. The Rimflex is a one piece gasket which makes installing it a little easier, and it is a little more forgiving then the stock gaskets. As for torqueing the bolts down with a torque wrench, I have never done that in the 40 plus years I have been messing with these motors for the reason you discovered. So I use a long wrench and tighten them down firmly. After a week or two of use, I retighten, and will generally go back a third time just to be sure.
