I used the PermaTorque Blue Felpro's when I repaired my head gaskets.  They work well because they seal any surface imperfections on the block or heads.  The MLSTM require a perfectly smooth sealing surface. You would want to get the block and heads surfaced if you plan to use the MLSTM.
Clean the block and heads really well with a razor blade and use the PermaTorque Blues with new torque to yield bolts

What year 3.8? I'd go with Felpros or Ford ones (which I think are Felpros anyways).

They list 2 cheap and double the price ,So is cheap the way to go?,I have not pulled the head yet,I owened two 3.8's before never had a problem,I know about the bolts,I guess I'm askin what you all have best luck with.Anybody got a part # I could use?,That would simplify it.As you can tell I am not a 3.8 guy.

Buy the high end Felpro ones that are Permatorques and not MLSTM.  Don't buy the off brand ones.
