<x-flowed>Scotty=> first thought is to check valve settings in the morning...any 
other ideas?

That's a good thought, and while you're in there check torque on the 
valvetrain and the head studs. To be more thorough, you might pull and 
inspect the push rods, but a problem there is unlikely. Also check for a 
loose exhaust flange.

Use the long-screwdriver-in-your-ear method to locate the sound more 
precisely, that might tell you something.

The scary possibility is a rod bearing, which can seize, leading to vast 
unpleasantness, so you're right to be careful about driving it until 
you've diagnosed it properly.
