I'm not yet sold on it being a head problem. The 3.1 engine is well known for blowing its' intake gasket which allows the coolant to flow into the fuel intake and down into the oil through the engine valley(location of push rods and lifters). All the symptoms you mentioned would be there and out of all the 3.1's I have seen over heat this was the problem. However, if there is solid proof that the head/gasket is the problem (such as failed cylinder compression test or a cylinder leak down test) then you or a shop would have to check the head for warpage before machining or replacing it. If you choose to check it your self then what you need to do is acquire a feeler guage and a precision straight edge. Set the straight edge across the heads surface and try to fit the 0.002 inch feeler between the two. Do this in several angles across the head and if you get more than the 0.004 inch feeler to fit between the edge and the head surface then it is warped and needs resurfaced or replaced.

Aluminium Heads can be straightened, however it is important you get a machine shop that knows how to do this correctly.
The process involves heating the heads up usually using a tig wellder to take most of the warp out, the important thing is that where the camshaft runs in the head is straight. Once this is straight then the head can be machined to surface the matting surface.
If the engine has not been overheated you may only need a gasket, this will depend on how well the engine has been surviced in the past.
The main thing with alloy heads is to use the recommended coolant.
Hope this helps.

you'll get a used one out of a low mile damage for a truthful cost. The aluminum is liable to warping. If that's been leaking awhile it would were slowly getting hotter and the oil would have had signs and indicators of water - which will be a head gasket..if it purely went quicker or later, a cracked head. If it had water contained in the oil for a even as because of a leaking head gasket, the engine might want to correctly be on that's totally last leg and a used engine might want to correctly be somewhat better than replacing a head. Get an section that works out of his abode to placed the engine in, it will be a extra useful option in case you'll locate one low priced adequate. =======================

What truckford said. You can't really check the head for truenss with a straightedge. It takes a large true surface and a feeler guage.
They also don't heat up heads to straighten them, that was funny.
This job requires a head gasket repair kit that includes head gaskets, intake gasket, valve seals and many more small gaskets. You will also need new head bolts. I would price everything out before you make your decision. Maybe you can sell it for parts... SORRY.
If you have a garage do this, it may cost quite a bit.

The symptoms you are describing point to both problems. You will have to take off the head to find out if the head is cracked. Take it to a machine shop and have it magnifluxed to check for cracks that are not apparent. You can check the trueness of the head by using a straight edge. If everything checks out okay, then all you have to do is replace the head gaskets and bolts and torque them down to specs.

usually after you pull the head to replace the gasket, you would send the head to a machine shop for inspection.They will tell you if the head is warped or cracked and if it can be repaired.If you don't send it out, you are taking a gamble.
