4D56T head swap details?

This is the head that you want because they are a reputable company and they do not sell cheap chinese crap. Yes I have used them in the past and there heads are great. They are also compatible with the 1984-85 injectors. If you have a 1983 diesel then you will need to pickup new injectors as well.

I also think i need to replace the head on my 83 ram 50 4d55 so im trying to get to the bottom of this. this item says flush type valves, though what im seeing most people say is that the older 4d55 had protruding valves.

what i dont understand is why this isn't interchangeable? the protruding type say the protrude a whole 1mm! i imagine it'd be fine to use this flush type head on my truck but i dont want to run into any problems!

does anyone know for sure what the interchangeability of these heads are?

Spence, I bought a 4D56 head from a different ebay seller with the same UK address (108 fishponds road), back in 2012. I wouldn't say it was complete crap, but I'm pretty certain it is from China. I do recall using a torque wrench to tighten down the rocker shaft to the head, and stripping out some aluminum. Luckily, the part that got stripped out was an aluminum piece that was used to hold down the camshaft, so I believe I may have just replaced that with a similar piece from my 4d55 head.

Anyhow, I would trust that this head is good enough, but I don't think it is flawless. So far I have had no problems with the head, but at the same time, I don't put a lot of miles on my truck.

so no replies?? This head i assume is flush mount valves and we need recessed valves for our engines correct? this says 98-05 shogun and L200 and we need the 93-98 style correct?? so this will not work without changing pistons??

I think flush valves are the same thing as recessed valves. Regarding your other post: I believe it was the 4d55 and the early 4d56 that had protruding valves. I think the later 4D56 had the flush valves.

I also think i need to replace the head on my 83 ram 50 4d55 so im trying to get to the bottom of this. this item says flush type valves, though what im seeing most people say is that the older 4d55 had protruding valves.

I think a protruding valve would mean slightly less room in the cylinder, which means slightly higher compression, would be my guess. Therefore, a flush-valve head would be slightly lower compression. And then the other problems would be if you got too late a model head, the injectors might not fit is my other guess, because they eventually started making the 4D56 as a common rail direct injection system, which would mean a head redesign (no swirl chamber at the very least).

...
Is it a direct bolt it for everything -- intake manifold, exhaust manifold, injectors, glow plugs, valve cover, and all? I'd be replacing it in a location that's about an hour drive from the closest hardware store, and even farther from a good hardware store or auto parts place (where the truck died, about 700 miles from my house). So, I want to be sure I have everything before going out there

Is the head that says flush valves for the 1993 to 2004 a compatible one, or do I need to find an older one? Do I need a composite or steel head gasket?
...

I don't know 100%, but I believe the intake and the exhaust manifolds would probably the same... however, at some point, they started making the 4D56 in a Direct Injection style, so I would guess that the injectors would certainly have changed at that point. (pure speculation on my part) Since you have a 1984, it should have the same injectors as the protruding valve 4D56. Beyond that, I can't say.

If you want to play it safe, then get a head with protruding valves.
Otherwise, make sure you check the injector size matches the size listing on the auction page.

When I bought mine, it was 285 UKPounds ... I see that c_heads_r_us is now selling one for 1295 UKPounds. That seems awfully high to me. I can see why you are considering the later model one. I wish I could assure you it would work, but I don't know enough.

Anyhow, if you look at the listing that Spencer posted, you'll see that it includes 4 injectors, so that makes my concern kind of moot I suppose.
