Porting a Zetec Head - Scorcher000 - 03-30-2013

As Brandon said above yes the head is getting done too.

It is not finished but it is scraped out as much as I would like to on the Exhaust side of the head. And I am only doing what is necessary to increase airflow. In this case on the Exhaust side I figured it out to be roughly 20-25% more flow.
It still needs the Intake side scraped and polished and then the whole head cleaned and sanded smooth.
Also look on the far left port at the bottom of the inside of the port. There is a letter "C" in the metal. I thought it was kind of weird but then thought, hmm, the coolant much run underneath in the channels below.

It will look better when I acid bath it and don't worry I won't let the seals dry out or metal rust lol I will keep some fresh Amsoil on them.

Looks nice. I worked at a plant that machined the 5.4's and 6.2's for ford and the heads look so good when they come out of the cnc.
