79 GMC 4.1L 250 Cylinder Head Advise

[79GMCSierra]

Hi All,

After doing a through inspection of my new purchase I discovered the the cylinder head is cracked on the exhaust manifold that is part of the cylinder head.

I believe this head is known as an Integrated Head. Please correct me if I'm wrong.

Anyway I'd like to replace it with a Normal I6 head that has a separate Intake Manifold and Exhaust Header.

My little bit of research tells me that a 78 head might be what I'm looking for. Or as mentioned on another thread a 194 Head. More info on the 194 head would be greatly appreciated.

So what might be your recommendations, keeping in mind this is a California truck. Funny thing is... I just had it smog'd and it pasted with the cracked exhaust manifold.
