Did you check/resurface the head for being warped when you removed it for gasket replacement?....

If it's warped then you can lay a sheet on Emory paper on a good solid flat surface and using a figure 8 pattern using your hands to sorta grind it back flat....if that's the problem. Of course you might have a pin hole in the cast aluminum somewhere that's causing the leak....
