I keep getting error codes due to a broken bolt on the exhaust manifold. It is either blowing out or sucking air in and showing a lean code. I have been dealing with it until last week. I have a injector or two that have failed or plugged up. I tore this thing down, I have ordered new Ford injectors. I pulled the head to drill out and repair the broken bolt. Come to find out I have one on each side broken. While it's down I decided to port the heads, intake and exhaust manifolds. I am not keeping this motor so I did not order headers.
I have come to the understanding that not much improvement will be made. I will say upfront that the lower intake and exhaust manifolds are more of the lack of power issues than the heads are. The heads are hopeless by design. If a guy was really determined replacing the valves to a race style would also help. I am simply entertaining myself with this and I will also wrap these manifolds to help to keep head down under the hood till I do my replacement swap. I have ET and speed numbers from when the truck was running it's best. I will check for improvements when done. I will also post pictures of the porting work.
