Contour Enthusiasts Group Archives Forums Modifications 3.0L Duratec Finally have the finished product.......

I spent days getting the ports to match the LIM and rebuilding the upper and lower edges of the gaskets surfaces. The gasket lays over beautifully and the intake runners are funneled down evenly to the valves ports. I polished the living day lights out of the exhaust to mirror reflection anbd widened the ports up and narrowed down the split some too. I am very satisfied with the results so now I am going to send the head to get a 3 angle job done.



And one quick question for most I wrote down the number like 1L 2L 3L etc for the cam caps when I took the heads down. When I put them back on I noticed they had (2) 4L but when I took them down noitcing this I wrote down the three digit number too so I could distinguish the two. But After observing the caps is it possible that a mechanic on the 3 liter motor replaced one while it was in the previous escape. I know it came out a wrecked car too. I will plastic guage the caps dry and make sure the gaps are right onb. Plus afterwards I will prelube the cam and then place them in the heads without lifters and see if the cams spin freely torqued up. It sucks when you don't know who did what to the engine previousily. But note I did completly rebuild the 3 liter even boring it over .020 too. along with the crank balanced and polished too. Thanks for the info guys on the oval port conversion can't wait to get some 400 whp ++++ soon.

Very very nice . Can't wait to see the finished product.

Did the cams spin freely? If so, I wouldn't seat it. I noticed the 3L heads in my car had either no markings on them or dupicate numbers I just put the caps back on the head after pulling each cam to make sure they went back on the same way they were intended.

I did put the caps exactly as I got them off just makes me wonder why the factory would not duplicate the same principles as the others. I did notice that my 2.5 liter heads had no duplicate labels and were exactly in order too oh and were stamped clearly. The ones that don't have stamped numbers do just they are so weak that you have to rub it and read it at an angle or they were stamped off center. wake up ford like to have some consistency. I didn't try the cams yet they are the valve shop.

On my 2003 block, there were two out of order caps on one of the camshafts. I'm going to put them back on in the same way. If it ain't broke...

Mine all got mixed in a bag...long story and I could only make out about half the numbers for sure about half of what was left had some illegible markings and therest had none.

as long as the cams spin like hot corn in butter...you're good.
