Default 2.2 Block Substitute for a 2.5 Block?

2.2 won't swap in after 2004, I believe due to differences.

And there are 2 'Phases' of the 2.2: 1 and 2. Make sure the 2.2s are 1999+

NOTE: The 2.2 had single-port heads on the exhaust >>2.5 is dual-port so you'll need that exhaust manifold from the 2.2.

ALSO, your Intake Manifold (IM) will only fit the '99+ SOHC 2.2 and 2.5, which is why you can't use the earlier 2.2 LONGBLOCk.
Well I do apologize! my head is not in the game. The 2.2 are coming from two 1999 and one 2000, I will be installing into two 2002 Imprezas. I was just going to use the blocks from the 2.2 and swap the 2.5 heads on and intakes.

So would you suggest just using the whole motor and swap the manifolds? I figured they were all about the 160,000 miles so I was figuring on head gaskets that is why I figured on just swapping the heads. I don't know honestly that much about the 2.2 motors and if they have the HG issues as well or not. Another yard just hit me up they have a 2.2 as well....hope this is feasible cause I will snag as man blocks as possible lol

Thanks for the fast reply too, greatly appreciated!!
