I'm interested. What's the last revision? DC? Differences? The other thread you posted in the OP says has to be 05'
Sorry, dont know a ton about the aviator head and years.

Bro you really need to unbolt the cam caps and show everyone that the cam bearings are still good. I already learned this lesson the hard way when buying a junkyard set of Aviator 4v heads. The front 2 cam bearings on the intake side were scored up real bad. Probably because some dumb house wife didnt change the oil for 6 months. If the cam bearings are bad then the heads are junk & useless. I talked to Ron Fox lake a while back about this and he said your talking $400 in machine work to try to fix them and still they may not be right.575$
Sorry man I didnt mean to derail your train, But this happens a lot, when I got this set of 05 Aviator DC heads off a running suv shipped to me from a salvage yard and saw the cam bearings scored on both the cam caps and the head, I then called Ron at Fox Lake, He said just the week before a guy sent him a set of heads and it was the same thing.Damn, I should probably un-package them and do that. Talk about a pain in the ass. Good advice though thanks man. I will do that.
No worries at all man I do appreciate the information, it’s just one thing I just so happened to not look at. I’m gonna take a look tonight and update the thread. Thanks for the heads up.Sorry man I didnt mean to derail your train, But this happens a lot, when I got this set of 05 Aviator DC heads off a running suv shipped to me from a salvage yard and saw the cam bearings scored on both the cam caps and the head, I then called Ron at Fox Lake, He said just the week before a guy sent him a set of heads and it was the same thing.
So I figured before you sell them and have the buyer pissed off at ya, you might as well check them out. If they look like this they are unusable and they arent worth the money to try to fix.
