My head questions
Hi all
Just had my head rebuilt and, well I'm not very happy with the work the guy did. To start with the guy has "0" personality and I mean 0 so after I had talked to his brother about doing the block (he's ok) he introduced me to his brother the 0 guy. So when I got it back I really didn't want to get into it with him, I still might go back and give me my two cents.
Anyway, I have a question about the head on the exhaust side. You have those 4 tubes on top of the exhaust ports, I'm not sure what they are called but I believe they have something to do with emissions, the ones you end up blocking off. Looking inside the head in those 4 tubes, 3 of them are broken and 1 is I guess long the way they used to be (see pics)
Can i and how do I remove them? It seems to me that these tubes would hinder the flow of the exhaust
I should mention this is a 20R head
Advice
Thanks

I do not think I have ever actually seen those in place.....
Drill the top flares off and pull them through, Or mini air saw, cut the end inside of the exhaust port and pull them out.
They are for the air injection. I do not know why they go so far in, when they are supposed to be helping the cat.

Yeah, I don"t know and don't know why they look like they were blown up at the ends? Very strange, like a lot of other things on this truck.........
