What heads are these?

They are early heads, I know that, but what do you think they are from?

DOHC with hydraulic shim lifters, like the 2.0 twin turbo heads, but these have a "coin"/shim on top of the hydralic shim, with NO numbers on either part.

Are you sure that there is an HLA inside of there and not just some gallies for oil circulation?

What are the casting alpha numerics off of the exhaust side of the head?

Where did you get them? Any history on them?

Sorry, they are NOT hydraulic

The exhaust side says LH NA and RH NA. The only numbers are 03 on one head and 07 on the other.

Ebay, $95 shipped, no cams but I got cams that fit them (I think) off another auction for fairly cheap.

Look like Phase I 2.5 NA heads. The pipe on the right side of the top picture looks like the EGR.

Be sure to adjust the lash when you put the new cams in. It will be a pain becuase you will have to buy new shims or grind a little off the end of the valve stem.
The Shims should be labled.

Are they tapped for the oil feed line?

I would say NO because they are marked NA.

Turbo heads have a B there.
