| Post subject: | EGR? Port on 1975 head |
First off I apologize for not being able to search the forum, I suck at it. I have a bare head from 1975 which appears to have an EGR port located at the side rear right next to #6 intake. This port is channeled to each exhaust chamber right below the exhaust valve near the stem guide. First, what is this port and second can I / should I block it? With each exhaust chamber connected to it I'm wondering the best course of action. Probably over thinking this... |

Nothing special there about "1975". But the original engine that head came from had an A I R pump, for smog control. You can block that off if it isn't needed. I have one here like that as well. One of my spares at the moment. The head I have with that port is the same exact casting number as the one on my most recent build that doesn't have it. |
