Not being negative at all about cooling around the spark plug hole.
It is a known FACT that the Ford Tunnel Port heads crack there, OFTEN.
That being said, doing your homework on a previously cut-up head would give you a lot of piece of mind, unless someone was afraid of the answer.

As I said before, Edelbrock has been casting up heads for Pontiacs and other brands for a long time without spark plug cooling issues.
I have minimal experience with wet flow testing but many years of experience with dry flow testing. I will leave the wet flow stuff for the experts.
