Now another thing, if you use 1/2" or 1" phenolic spacer you wont have to modify your upper intake to clear the fuel regulator, you might even be able to clear a proper fitting F-150 fuel rail on there too.

Nice advice neo, but as stated, those heads are still dirty, I wouldn't of taken them, I would of demanded that they finish the job. I don't have any old pics of my GT-40 X heads before I put them on the 5.0, but they were used, however fully rebuilt, and there wasn't a spec of dust on them, not to mention oil or dirt, when I got them.

The heads between the 3.8L and 4.2L are the same.
The windstar fuel rail does have a return line on it.
I think mine was a 98' if I remember correctly.
Here is one on ebay for $24.95 shipped, you cant get much better than that.

I will hit them with toothbrush and carb cleaner to finish them up. and from the pics i posted you can see the exhast ports are no were near the same size as my stock o1 heads.
I got my 2001 upper but i dont have a lower intake yet. so my question is what one should i use?
I will get pics of the motor and everything today.

take a ruller and measure the ports and compair, using the exhaust manifold gasket to check is just wrong! 
The exhaust manifold gasket is huge by any term and you should never port match to that gasket size.

01+ valve covers as the 99-00 allowed a lot of oil back into the intake system.
I still have to change mine, not a big deal though as I plan on changing my lifters and rockers and getting a 2nd t-stat sending unit installed on the lower intake.
I dont know if the BBK valve covers have this problem though, in case your into those kind of things.
