Airbox cover gaskets leaking

The airbox covers on the sides of my 8V-71T are leaking, presumably from the extra boost pressure from the turbo.  I have new gaskets, but I wanted to ask about the best sealant to help them out.  My choices would seem to be Permatex No 2, which is what I used on all the other gaskets when I built this engine, a product called Seal-All that I've used for the toughest leaks (I once exploded the spiders gears on a differential on a racing MG Midget, a couple of the teeth came out the back cover, and I used Seal-All to plug up the holes.  This was close to 20 years ago, I saw the car last month and it still has the Seal-All repair on the holes on the axle...) and Loctite "The Right Stuff", which is a non-silicone gasket maker.  Any thoughts on air box covers on a turbo'd engine?

Thanks, Brian

As soon as the tool arrives I am ready to ship I should have a set of the covers made of 3/8 steel from a transit engine not the cast I'll toss in the box that will stop that little problem

Brian, don't use any sealer on the air box gaskets the new ones come with a coating on them use the steel covers and new bolts with a little Loctite and get them tight.
