just snug.
not very tight... the rubber gasket on centerbolts doesnt have to be squshed hard to seal... and the small bolts holding the valve cover are easy to break off into the head if you try to crank them down.
if the bolts are weeping oil, goto lowes, home depot, ace hardware, ect.. and get some 1/4" copper washers.
the soft copper washers act as a seal.... after they've been compressed a couple times, they can no longer form to the cover and bolt, and the weep oil.
i paid 20 cents for a pack of 10 at lowes.... worth the money.
