Intake Coolant Leak

Alright. '72, 350, Weiand aluminum intake on stock heads. Had a coolant leak through the intake bolts. Replaced the intake manifold gaskets two weeks ago with the Fel-Pro gaskets w/ the blue silicone beads around the ports. Made sure to use teflon thread sealant on all the bolts.

Drove it for two weekends, no leaks. Drove it last on Sunday (now Thursday night so it sat cold for 3-4 days). No leaks (that I noticed) all week, today the overflow bottle was almost drained. Took it out for a quick run, water was pooling on the passenger side of the intake again.

The only thing I can think of is that I maybe overtorqued the bolts. I used a torque wrench on the ones I could get to w/ the wrench (cheap ass Sears beam-type that is too tall to use on all the bolts). Looks like (maybe) most of the water is coming from the front passenger side bolts. Should I bite the bullet and try again w/ a new set of intake gaskets?

Ideas? Thanks.
