SOURCE: tightening head
New Headbolts are recommended
Long bolts are torqued to 46'lbs + 90 degrees.
Short bolts are torqued 43'lbs + 90 degrees.
Start in the center, and work to the edges, torquing the bolts in two stages.
Rockers are torqued to 22'lbs.

The problem may very well be fixed by tightening the boltto the factory spec, but what you must realize is the gasket has lost its even shape from extreme temperature changes.being its now thicker in one area as apposed to the next thus causing the leak from shrinkage.retightening the bolts tro specs will mean you are sinking the bolts at an uneven level and possibly warping the pan from ever seating correctly when facing the enevatable and thats replacing the gasket. i suggest just replacing the gasket with a quality aftermarket performance gasket as apposed to the factory gasket from the dealer or local parts store.you will find the quality and reliabilityand the longevity of the performance aftermarket gasket will far eceed the limits of that of the stock one.i know this wasnt a solution to your problem but hopefully i have saved you several hundred dollars from having to replace the pan itself due to the warping issue.
