I have to ask, after you first got the engine up to opperating temp, did you shut it down, pull the headers, valve covers, etc., and retorque the head bolts?
Its an obsolute must with aluminum heads! A real pain in the a$$, but you would'nt believe how much they loosen. You could already have a blown head gasket.

I don't know about that. I worked as a line tech for a LONG time and I've done cylinder head work a LOT. On the line at the Ford dealer in Macon, I never once saw a factory TSB or anything that said aluminum heads required a retorque. Never. There are some special head bolt torque deestruckshuns, but that's all.
