In case you didn't see the post, I found some GT-40 heads and an Explorer intake for $350. So I went up to Pheonix yesterday and picked them up from the salvage yard (All Ford Parts). Today I took the heads apart and cleaned them up along with the manifold.
I noticed a few things: The valve faces were kind of white looking. I know when spark plugs are white, it's becuase you're running lean, but does the same go for the valve faces? I've seen some burnt valves and they were white, but also totally screwed up. These still look good, just sorta white. I think I can still clean them up. The chambers were still pretty black, but no carbon build-up.
I also noticed that the backside of the intake valves were pretty built up with black crust, pretty oily but nothing that can't be cleaned. In fact, the entire intake track was black and pretty grimey. I was able to clean it up pretty well, but I'm still wondering why it was like that.
All in all I got pretty lucky. The truck had come to the yard a few days prior to me calling them up so everything internal still had oil on it and no rust yet. The valve guides are still tight and the seats seem good so I'm happy.
