All you have to do is correctly answer, what is this head for.

Well it's one of several heads off some big industrial engine. I
don't recognize it though so I'm not sure of the make. It might be
Caterpillar but I doubt it.

Notice that the bolt holes for holding the head down are shared by
the head next to it. On big engines the heads often come in more than
one piece.

It's definitely not a air compressor head. The hole in the middle is
for the injector so it's a diesel engine head.

Don't ask me what brand it is, but this looks like a segmented head
(one cylinder) for a Big Diesel. Medium sized Earthmover or Class 8
Truck sized. They build the big ones like this so you can take apart
the one cylinder that has problems for repair without taking the whole
engine apart.

I'll be interested when someone pops up and says "Oh, that's a CAT
3608 head!" or something like that...

The head bolts go through the half-round notches on the sides, and
clamp two adjacent heads with one bolt and a big washer. Four holes
for pushrods up through the opposite sides. Hole for the fuel
injector in the middle.

Most likely the big siamese ports are the exhaust, the one that
loops around at an angle are the intake - if you have a turbocharger
or supercharger in the intake you can take a bit more circuitous
route. And the port on the top with the three bolts and O-ring groove
is probably for a coolant manifold back to the radiator from each
head.

And each head has it's own valve cover for the rocker arms.

I won't bet the farm on this, but my money is on a large marine or
stationary diesel engine like this....

Just for giggles, I checked out the spec's on Waukesha's largest engine

Igor, your cylinder head is not from this engine, the heads on this
beast weigh 450# each. The whole engine tips the scales at 63,800# dry
with no flywheel....but it does produce 4500hp.....

Head for a single cylinder 53 or 71 cuin Detroit diesel.
Greg

I suspect its a single head for a 2 stroke an industrial diesel engine.
They usually have one head per cylinder and poppet valves only on the
exhaust. The inlet valves are ports on the cylinder. It may be off a GM
engine like the old 6-71 tank engine but I don't think they had 4 valves in
the head. Its been a long time since I saw one.

Well I sent the link along to a friend whose business
is remanufacturing diesel engine heads, etc. It is his considered
opinion that it is off a Volvo engine...
The copper sleave in the center of the valves would be for the
fuel injector, and, was one thing that made me suspect it is not
a compressor head. Copper is REALLY bad for use in compressors,
as it work hardens and cracks really quickly.
