Default phase one 2.2 and phase two 2.2 compatability

I have a 1998 phase one 2.2 legacy and mistakenly ordered a 1999 phase two short block. I am wondering what will need to be replaced/ retrofitted... I have heard talk that the early 2.5 valve covers and intake manifold will fit the phase two 2.2?

Might want to post this in the N/A Motor section, or over at ultimatesubaru.org. Will get a lot more traffic.

I'll comment, but it's really only a guess. The block and phase 1 heads will physically bolt together, probably will be a compression change, which might not be a huge deal. Depending on your plans you might be able to put together a frankenmotor (google it). Phase 2 block, EJ25D Heads, and the intake manifold off your phase 1 2.2. Probably a few different ways you can go, there are folks way more knowledgeable than I, hopefully they will chime in!

Good luck!
