it doesn't look like you have SAI heads installed. maybe i just can't see it in the photo, but i'm not seeing the vacuum pump or the hoses that come off the head. if you don't have SAI heads installed and you have a SAI ECU you will always get the SAI codes unless you have the ECU reflashed to a non-SAI format.

If you have SAI heads, they will have 2 threaded holes between the spark plugs on each.
They should have brass tubes coming out to hook up to the rest of the SAI system.
Those holes can be filled with threaded plugs. And I've seen hack jobs of the tube ends from the heads crimped closed.
If the heads are non SAI in an SAI truck, then someone swapped the heads, or the whole engine, as they are notorious for overheating and blowing head gaskets.
I also have a good set of SAI heads from a running 4.6 if anyone needs a set.
