Eureka! I found it !

It has been driving me nuts looking for the source of my Mobil-1 Latte double-shot with extra whip cream in the engine. I know, it's a really short drive for me goin nuts..

Upon pulling the second head this evening....... AFTER winning an ebay auction for another pair of GT40p heads with GT40 intake manifolds, throttle body and injectors..........

I noticed a funny looking comma looking mark on the head gasket. Kinda curly like one of them fat curly hairs, really fat! Sure as shootin' it was a tiny water channel from a steam hole directly to the lifter valley. It would have been shooting coolant, then steam at the underside of the intake manifold, hence the fancy barista artwork on it.

Woohoo! Except for the extra three hundred bucks this has turned out well. I had wanted to score the GT intakes to cut up for a future switch to injection my way.
