That's the first suspect on an FE.....

Have him pull the spark plugs and see if he can narrow it down to any particular cylinder.

Did he bend down the head gasket tabs and has he re-torqued the intake manifold bolts after a couple heat cycles, and then again after a few more heat cycles?  I've learned the hard way on both of those.
