You really dont have to port the head. The biggest thing is shaving all of the cast marks in the ports smooth and giving the exhaust side a nice polish. I did all of that 20k+ miles ago and ive ripped the exhaust manifold off twice and no bullshit i can wipe the carbon out with a paper towel from the exhaust ports.
