I know this is an old thread but I just came across it and have $.02 to add.

The FF heads can be ported. Here are the FF rules regarding the heads:

FCS.D.2.c "Cylinder head. Ports may be reshaped by the removal of metal as long as the port diameter at the manifold face of the head does not exceed the following dimensions: Inlet 1.50" Exhaust 1.16" "

Clarification on edit--FF rules cont'd:

"The use of the Pierce aluminum cylinder head is permitted."
