Another what is it?

[Challenger6pak]

You guys helped me figure out a tail light set and a grille.  Now I have a head question.  Does anyone know what it i?  There are no casting numbers on it.  It came with a bunch of Mopar parts when I did a machine shop buy out.   It may not be automotive.  I found some tractor parts in the bunch already.  Thanks,
Tod

With the intake and exhaust ports on the same side, it's got to be a 4 cylinder head......................... looks like Chevy?

Do you know what year or make of GM?

[Challenger6pak]

I found a list of applications for the GM Iron Duke 2.5.  Is that what this head is off of?  The Iron Duke?

[72cudamaan]

The "iron duke" was a term given to the old "60's" engines. This looks like a mid eighties fwd version.
If you have a casting # I might be able to narrow down the year. But that won't tell what kind of car.

[72cudamaan]

Might be the early eighties. I see that the casting has egr tube bosses that haven't been opened
up for the a.i.r pump tubes

  I THOUGHT GM ALSO.I sell parts for gm so i'm trying to id the head.I checked the 2.5 82-87 and the port patterns are totally different.also the int and exhaust are on opposite side of the heads.

i'll do some more digging here at work as time allows.

  Do you have another pic of the non port side,also if it's a GM head, it should have a casting number somewhere on it. 

[TreeFrog]

Got me on this one!

[72cudamaan]

It's definitely a GM. You can tell by the shells over the springs.

[TinCuda]

GM, em, it does look kind of slow... LOL

I wonder if it's for that old pontiac tempest that Cooter posted awhile back. Can say I'm up on 4 cylinders esp with a cast iron head?
