    possible head upgrade *pics*

    So I may have found a set of D0AE heads from a 1970 351w for sale locally for $200. They're complete. The guy says it looks like they were rebuilt and never used. I have to get some more info, and he's going to verify the casting numbers for me. In the event I do get these, I'll need those bushings to use 302 head bolts in a 351 head, correct? Is this what I need?

    I wasn't able to find stepped bolts, but if I can, are those a better option or would I be fine with those bushings and a set of good head bolts? I was thinking of using a set of ARP bolts to replace my high mileage stocker bolts.

    These heads should also be stud mount rockers if I'm not mistaken. Is there any way I can convert these to pedastal mounts so I can use my current 1.7 rockers? I hate stud mount rockers. Reminds me of working on a damn Chevy motor.

    Lastly, and probably most importantly, how can I tell if these have hardened valve seats so I can run unleaded fuel in them? If they don't have them already, would it be more money than its worth to convert them so I can use them? I'm not planning on doing anything crazy with these. Maybe a little gasket matching on the exhaust side and install them with a stock HO cam.

    I ran a set of those heads for 160K with a three angle valve job. Once they have been run with leaded fuel it seasons them so to speak. Ford evwn knew this at one time and was going to put lead additives in the first few tanks of fuel then it would be fine to run unleaded. Unfotunatly it greatly reduced cat life and was nt good for the oxy sensor either.

      I believe ARP makes head bolts with a step. On the other hand I have run W heads on 302s for 100s of thousands of miles with out hat washers or special shoulder bolts. Turned engine in the 9000RPM range too.

        1996 Explorers used GT-40 heads with 1/2" holes and no stepped bolts or washers. The 2 sleeves per head apparently did a good enough job by themselves.

        The preferred thing to do is to convert to screw in studs. Converting to your pedestal style is very possible, but seems silly.

        You would be able to see the pressed in seats if they were there. I would use an additive instead of spending the $$ on converting the heads. The only time it makes sense is if you were having the heads rebuilt and larger valves added.

          I found a pair for sale in Jersey on GoDragRacing.com, same ones? The cost to convert the valve train brings them about even with GT40s.

            You are better off with the GT40 heads. Better exhaust port design from the factory, better rocker arm hardware and hardened valve seats.

              Maybe, I found them on craigslist. They are in NJ tho.

              This is all just an idea really. I can't run lead additive because I have cats, and I really don't want to deal with carrying bottles of the shit around anyway. I'm just weighing my options here to try and figure out what I want to do. I might go with something else, I'm just gathering information so I can make an informed decision on this.

              I can keep the current rocker setup tho. If its pressed-in, they stay that way. I'm not really looking to invest a lot of time or money into these. I just really hate going through all the bullshit of adjusting valves with stud mount rockers.

              Thanks for the input.

                Well, it looks like I'm getting them. They don't have hardened valve seats in them, but between info here and from talking to the guy that shouldn't be much of an issue. He says he has another set of these on his Fairlane and has been running them for years without issue. They are complete, rockers and all. These were intended as a spare set, and were rebuilt some years ago, but have been sitting ever since. They need to be cleaned up and should be ready to go. I'll pull the valves, install new valve seals, and put it back together. He's giving them to me for $150. Yes, I realize these aren't the absolute best heads on the planet, but for $150 its going to be really hard to beat the value. I'll skip the spacer things since the consensus is that I don't need them anyway and just go with a set of ARP head bolts for a 302. I'm not looking for miracles from these things, but it should be an honest improvement over stock e7 heads with a crappy valve job. I'm also going to pop my e7 heads apart and see whats going on with them and maybe experiment with them a little.

                Related to this, should I put new lifters in while I'm doing all this? Mine have something like 150k on them and the valvetrain is a bit noisy. I'm thinking the lifters might be tired. Thoughts anyone?

                  Picked them up today. They've got double valve springs on them already. These babies need some serious cleaning but I think some time with a wire wheel on the valves, some sandpaper on the heads, and a dose of lapping compound it might just be serviceable. I might have them hot tanked once I strip them down just so they're nice and clean for re-building. They were also lightly gasket matched on the exhaust side. Doesn't look like they have been run. Guy says he got them from a speed shop liquidation in the 80s and they had a rebuild tag on them. They've done little but sit around since then.

                  On an unrelated note, he's also interested in my VW stuff, so it looks like I can get all that crap out of here and put some cash back in my pocket. I'm taking a hell of a loss on it I know, but it needs to go, and I haven't used it and won't use it for a very long time. Might as well sell it and use the money for other crap while its still worth something.

                    Can anyone tell where I painted my last water pump?

                    I was also wrong about the casting number. D0OE, as you can see.

                      The amount of rust justifies bringing them in for a quick cleanup. Your guides could have issues and I really wouldn't go nuts with a wire wheel in the chambers. Those springs should be tested at installation height. They may be original factory springs. The inner is just a dampener. If any meat was or will be taken off of the heads, you will need to convert to an adjustable valvetrain. D0OE and C9OE 351W heads are pretty much the same head. I have even seen a bone stock late 1969 model year motor with one head of each casting on it.

                        Look stock to me. Rail rocker with press in studs. They need a burn and blast, deck surfaced, .........

                          I wasn't going to wirewheel in the chambers, just the valves themelves on the shanks to clear the rust from them and off the head. Probably the chambers will get a brass wire brush or scotchbrite treatment.

                          What do you mean tested, with a spring guage to see if they're still at proper tension?

                            You need to take them to a shop and have them done. There is probably a few valve not serviceable. Metal transfer from valve to seat. Not a bad core price for those heads.

                              I'll pull them apart and see what they look like. Might you have an intrest in doing them for me? If so, any ideas on a cost?
