2007 5.7 based 399c.i. stroker build exhaust bolt pattern problem

Greetings!
I am in the process or stroking my 2007 Ram 1500 5.7 to 399c.i. I ordered rebuilt Eagle heads to work with my dished CP pistons for 10.75:1 comp ratio. I ordered Pacesetter 72C2211 Armor Coat LTH to bolt to the eagle heads, but something is wrong. I know there are different castings for right and left hand side heads - I made sure and got both a 53021609DD and 53021609DE so I would have both heads, but there is one bolt pattern for both sides. The first three ports from the front (waterpump end) of the engine on both header flanges slope towards the front - the rear port on both heads bolts slope to the rear. My heads have the same exhaust bolt pattern on both - on the drivers side the front three exhaust port bolt slope to the front and the rear slopes to the rear. On the passenger side, the rear three exhaust ports slope to the rear, the front port slopes to the front. They are marked differently as far as casting numbers. Can anyone explain what is going on here? Did I get an incorrect head casting from the rebuilder? Pics below.

Passenger header held up to passenger head - this is the one that has a conflict with the bolt pattern:

They wouldn't load on my phone just now either, but loaded just fine on my PC. Wonder what's up with that?

Here's a link to the google photo album.

You can post the pics from your pc. You'll get more people interested in following your build if you post them on this site.

Believe you have two drivers side heads. Look for a rear lower oil drain hole on the passenger side head. Also no egr port on your passenger side head. I'll take a pic of my 6.1 passenger side head and post it up.


PS. The same thing happened to me when I bought my 6.1 heads.

You should use D port headers. Square port could have exhaust flow and gasket sealing issues.

I thought Eagle heads did not have an EGR port?

Everything I have read says 2009 and newer headers will not fit on my truck without major modifications. The gaskets that came with these pacesetters have a round hole that does not cover any of the D port in the heads. I had planned on using a carbide burr to chamfer the top of the header flange to ease the transition. Have you had a different experience? I have none - just what I have read... so I would defer to experience. Thanks for the help.
