Not saying i agree or disagree with the head porting thing, because honestly, i have no experience with theses heads, so i really have no clue at the moment, BUT... IF any porting were to be done to the head, it would be done by me... meaning it would cost a big whopping zero dollars. So, i really dont think it could hurt.

On a side note... I also look into different options when porting, like making a custom manifold, and raising the floor and ceiling of the port for a more direct shot into the cylinder. But as i said before, i haven't even seen what the ports look like yet, so this may be impossible.

Also.... how much can you safely deck the head to raise the compression? and would it be safe for 91 octane? with a tune of course.

I have a bridgeport milling machine at home with a nice fly cutter that i have decked many a head with.
