Default Screamin Eagle heads

I'm trying to identify the heads on my 2002 883-1200 bike before I take it apart. They have Screamin Eagle etched on the top fin on the primary side and it looks like the rear part number is 15577-07 but it's hard to see. Maybe 16677-07 or maybe ends with -01.

I know its a long shot but does this ring a bell with anyone? Specifically trying to find out the combustion chamber size.

I think you already know they are SE heads.
The -07 casting number rings SE Pro to me.
Here are some pics in the Sportsterpedia for those.

edit:
I just checked my casting numbers on my SE Pros (they are not part numbers), rear- 16877-07, front- 16874-07

I can't for sure make out the casting numbers in your pic.

Thanks again HippySmack. I wish I had your knowledge but I'm trying to learn.

Don't look at me. I'm ignorant. Ask anybody.

The EFI versions of the SE heads have the -07 casting number. The carbureted version (16500164) have a -02 casting number.

Odd that you would have the EFI version of the SE heads on a carbureted bike. Standard carb type manifolds aren't quite wide enough to work properly with EFI heads.

Aaron, the casting numbers I posted are the same heads that you guys punched the second plug hole in for me on my carbed 1250.

I put these in SP but I can get closeups of the castings (-07) if need be.
No problems using my stock carbed manifold.


edit:
Below are the casting numbers for my carbed set.
Are the casting numbers for EFI the same? Don't seem they would be but stranger things have happened.



Just for a visual, EFI intake mounting holes are spaced wide enough apart that the distinction between them is pretty clear.
