Replacing heads on an '05 6.0L with '04 Oil Rails?

[mchan68]

I have a unit here that is getting new heads and both coolers. I always found it interesting that with each new head, comes the gasket, dowels, as well as standpipes for '03 model year applications an '05 to '07 model years. This means that for '04 model years you either need to order a new standpipe or reuse it. The truck in my bay right now is an '05 model year (that's a LATE build '05 with a MAF). But it appears to have '04 high pressure oil rails that use the 1/2" square drive to remove the standpipe and dummy rail plug as illustrated in the photo below on the right, compared to the one on the left, that uses the 10mm allen key to remove.

But, when you line the three standpipes up together, it doesn't look like the later '05 to '07 style standpipe can be used in place of the '04 style, when you see the difference in lengths. Anyone care to comment?

Just curious. Has anyone else ever had an '05 truck apart with '04 rails like the one in my bay right now?

I have had a couple and I used the new style that came with the headgaskets. I didn't have any problems.

There should have been a note with all those parts, it basically states the length variances are ok and to use the new 10mm style tube.

The truck I just did was like this, I used the new-style tube with no problems.

 

Come to think of it, the last truck I had apart for injectors had early style on one side, and late style on the other.
