39 Head torque

[rotorwrench]

Ford actually restricted some of the ports for a reason. This way they could control the flow around the cylinders and especially through the head a bit better to relieve hot spots. The 8BA blocks had larger ports at the back of the decks to flow more from rear to front but it made the decks a bit weaker. I don't get real worried about the gaskets changing the coolant flow.
