WTF. Car keeps overheating?

There are some small differences in the casings especially as the later years progressed.  To my knowledge the 2.8 vs 3.1 differences are attribuited to mainly the crank and the wrist pin height in the piston.  Thats basically it so 2.8 heads should work fine.  This is all what I have been told.

I knew the crank was different, and thought the heads would be close enough to use. So thats good we will find out at a later date. Thanks Ken

Well guys here is an update on the dogginred90. She got tore apart yesterday and found both head gaskets were blown. Upon further inspection of the heads I found both were cracked. UUGGHHH. But got a set of 2.8 heads that the machine shop said will be done tomorrow, so it will be back on the road tomorrow evening again.

I just did headgaskets on my 6000's 3.1.... I hope my felpro headgaskets dont blow, lol, are you pretty sure your heads just were no good then?? My gaskets just blew, no overheat nothin, just pullin a steep hill gave her abit too much throttle and pop! The heads were flat and in good shape i just reused them.

I am thinking the heads were shot before. I just didnt see it then. The machine shop cooked them and found the cracks. 4 cracks where the spark plugs go, and the rear head had 2 cracks from the water jackets. There were more cracks on the rear head, I take it that one is the one that got cooked from overheating. I guess it just took time for the gasket to give before the second blow. LOL. 2.8 heads are good from what he says, so it is going to be good.
