retorque heads to solve issue?

For the guys with head gaskets weeping oil, where do you think it’s coming from? The lifter galley? It makes more sense to me that if it was going to weep it would be coolant.

Guess I’ve been lucky, built my first small block in 1977 and several more over the years. Big blocks too and have never had a head gasket weep or blown for that fact. The only one I have ever retorqued is my current 434.
