Default Replacement Short Block ID

I have a 2003 Outback wagon with the normally aspirated 2.5 engine. I have bought a used short block to put in it.



The used short block has these markings:

Rear of engine, top of flange which goes against the bell housing:
9641189662303

Rear of engine, top of flange which goes against the bell housing,
left half part of the block:
C288213

Also, stamped in a sort of ink:
top rear of block, right side half: 2004 08 07
top rear of block, left side half: 2004 D8 06

...Please help id this engine..it's a 2.5, but date of manufacture ?
A block for a NA engine ?

...I'm looking for confirmation that the block can be switched out OK with my existing short block which is presently in the wagon.

Thanks..

The VIN should be stamped on the side, of the right side of the bell housing. That will tell you what it came out of and what year.

On the side of the right half is the block is stamped:

JF1SG63615G725196

this is a VIn number I guess but I can't decode it.

Will the compression ratio be any different ?

And if the block is a 2005 ( Forrester ), what year(s) STI headgaskets should be used ?
( Of course I'm going to be using the original heads out of my 2003 Outback wagon )
