RTB Posted January 17, 2014 Report Share Posted January 17, 2014 Im not a expert on head so I'm going to post some pictures of a 219 head I've been offered and if anyone sees some major problems please let me know Quote Link to comment
MicroMachinery Posted January 17, 2014 Report Share Posted January 17, 2014 Its been milled. How much? I dont know. Quote Link to comment
RTB Posted January 17, 2014 Author Report Share Posted January 17, 2014 Its been milled. How much? I dont know.I'm trying to get a thickness from the owner but the problem is that he is in Finland so we might email 1 or 2 emails a day max. Sucks. Quote Link to comment
ggzilla Posted January 17, 2014 Report Share Posted January 17, 2014 You can tell from the photo how much its been milled. The '219' is cut off on the bottom about 2mm Quote Link to comment
RTB Posted January 17, 2014 Author Report Share Posted January 17, 2014 There's no point to get this head right guys? That was my initial thought, that it had been cut too many times. But I wanted to be sure so I posted it here. Quote Link to comment
hobbes_the_cat Posted January 17, 2014 Report Share Posted January 17, 2014 I have had motors run good with that much of a cut so I don't think that alone should be a deal breaker but i wouldnt plan on being able to cut much more. Cam tower should be shimmed for sure though. I think price should dictate if you walk away or not. Quote Link to comment
ggzilla Posted January 17, 2014 Report Share Posted January 17, 2014 As long as it is flat now, it doesn't need to be cut again Quote Link to comment
RTB Posted January 17, 2014 Author Report Share Posted January 17, 2014 Trading my 4.625 LSD for this head and a straight intake manifold I can't seem to ID. So I guess price is shipping from Finland. I have no way to tell if it needs to be cut or not. And that's what worries me most. If there's a problem I'm fucked. I will have a useless head and he will have a working rare diff. Quote Link to comment
wayno Posted January 17, 2014 Report Share Posted January 17, 2014 OK, what I see is that the head has been milled as mentioned, but what bothers me is that the valve seats look like they might be touching each other now, I don't know if it has bigger than stock valves, or if it has been rebuilt so many times that they are touching now, you see each time you change the seats, the hole they sit in needs to be made slightly bigger, so if they are touching now, it's a lot harder to deal with from the machinists point of veiw. Once they get so big, I believe the head is scrap, but I don't know that for sure, maybe there is a trick I don't know about. In the photo below, I cannot run this head till it needs new seats, I need to stay on top of it, as they are touching each other, but I have 1 3/4 inch intake valves in this head now.

RTB Posted January 17, 2014 Author Report Share Posted January 17, 2014 I didnt even think about the valve seats. Quote Link to comment
wayno Posted January 17, 2014 Report Share Posted January 17, 2014 I didnt even think about the valve seats. That head looks like it has some really big seats in it, I would need a photo of that cleaner #3 cylinder up close like my photo above, something that my machinist could see to give an honest opinion. This is what my 219 head looks like, and it may be shaved also, just not as much as that head. Quote Link to comment
RTB Posted January 17, 2014 Author Report Share Posted January 17, 2014 I'd say yours is a good 6-7mm thicker than the one I've been offered. Quote Link to comment
RTB Posted January 17, 2014 Author Report Share Posted January 17, 2014 Nevermind guys. Troy found me a guy willing to trade his brand new still in the box 219 for my diff B) Quote Link to comment
wayno Posted January 17, 2014 Report Share Posted January 17, 2014 I have never taken this 219 head in to have it checked, it could be scrap that someone sold for money(ripped me off). There are lots of avenues to take to make a performance engine, if your boring out the block, you can buy pistons with less dish, and use a U67 head, and they are a lot cheaper than a 219 head. 1 Quote Link to comment

EricJB Posted January 18, 2014 Report Share Posted January 18, 2014 Something not right with the seats. They all look oversized. Last chance. And the clean cylinder appears to have the intake seat staked in. Not good. I would seriously walk away. Quote Link to comment
RTB Posted January 18, 2014 Author Report Share Posted January 18, 2014 I did walk away. Getting a brand new head for my diff. Lucked out. 1 Quote Link to comment

It looks like all the intakes have them marks except for maybe number four, can't tell from that photo. Quote Link to comment

It looks like all the intakes have them marks except for maybe number four, can't tell from that photo. Valve seats in aluminum heads should be put in with about .005 interference. Then you heat the head to 300f and freeze the seats in nitrogen, or Co2. I put them in our big freezer in a jar of acetone. Then beat them in with a pilot and a BFH. Seats that are staked in usually weren't installed correctly to begin with.They could be welded up and remachined, but time is money. Congrats on the find. Quote Link to comment
RTB Posted January 19, 2014 Author Report Share Posted January 19, 2014 This looks much better. Need to source steel intake valve guides. Quote Link to comment
datzenmike Posted January 19, 2014 Report Share Posted January 19, 2014 Usually they are bronze aren't they. Steel on steel??? Quote Link to comment
RTB Posted January 19, 2014 Author Report Share Posted January 19, 2014 The seller claims 12 years of building and racing experience plus his dad was in the comp department in the 60s and 70s. Claims that I need steel valve seats. Quote Link to comment
EricJB Posted January 19, 2014 Report Share Posted January 19, 2014 Hardened steel seats, bronze guides. Quote Link to comment
