I'm having a hard time with determining left a d right on my heads. Some say only one is drilled for the egr, one says you'll cover an oiling gallery if they aren't on right and one guy said the only thing to make sure of is that the power steering pump will still bolt to the head....it's a 2011 5.7 hemi.

 

I’m sure you know what you are talking about but your not very understandable in your post. Please if your asking a question try it again.
thanks

 

On a 2011 5.7 hemi, how do I distinguish which head goes on the passenger side and which goes on the driver side. Or, does it matter?

 

Do the heads have different casting numbers? I do think that they are different for each side..
