Andrew,

With all do respect, most head volumes listed by NHRA do not hold the factory volumes. The head was submitted and pored, just like many other heads.

I am not sure why you think the head specs listed by Ford Racing in their parts catalog has any relevance with what NHRA has posted. They also list flow number, but we all know they follow much better.
