Seems I never can find one machinist that can do it all. I located another guy here who says he can do all that I want but take down the log for the 2 barrel upgrade. He began by just looking over my head and then he say's "those intake holes and seats have hit their limit!". Then I respond, how so? Well whoever has been workin' on that head didn't leave any valve seats to work with---those things are huge. Then I said, no one has touched those seats that I know of, if they did it was not because I told them too. I didn't tell him I have 3 other heads just like it and they all look the same at the seats. He goes on to say "I would be very surprised if they did'nt cut into the water jacket opening those up. I would recommend a 30 dollar pressure test before I did anything. Then I told him that I had a guy magnaflux and pressure test it already and they didn't find a thing wrong with it. Well, are you sure they pressure tested it?? I then said, look the hot tank was down so they cleaned it up the best they could with what appears to be some type brass/bronze medium and then they magnafluxed and pressure tested it. Well magnafluxing it doesn't mean nothing, you better be sure they pressure tested it.
Then he says at any rate if I was to do what you want I would just take those hardened seats out of the intake ports and leave your exhaust seats and clean'em up a bit. At this point I asked him what the charge would be for doing all but the log opening. He then gives me a quote of $180.00 for milling .015, putting in my teflon valve seals, cleaning up and taking out my valve seats, 3 angle valve job and putting the whole thing together. Then he tells me my 351 windsor valve springs (exh.) are too much, then I tell him they are 200 open and 80 closed, yea he says that is pretty stout but 80 closed ain't too bad. Finally I tell him about the cam I am going to use and then he backs off a little, saying yea, that's a pretty stout little cam for this six, probably will handle that spring...Now after all this I am a little suspicious of what this guy actually knows and doesn't know, I have a stock '78 head--looks just like the others I have in my garage---his price is fine, no question that $180 bucks with the pressure check is a good deal. My question is do any of you think I should trust this guy with my head, I have already cleaned up the chambers and ported???
