Default v7/v8 JDM intake manifold -> Phase II SOHC heads?

Searched and searched to no avail- can anybody verify for me that I can bolt JDM STi intake manifolds to my RS heads? I thought all Phase II parts could be pretty much mismatched as you please to some degree or other as far as heads, blocks, and manifolds go, but I have heard rumblings otherwise. The purpose is to put nicely a flowing manifold on ported/cammed SOHC heads on an EJ257 block for my true RS-T build (as opposed to EJ20/STi engine swap).

Secondly- if you have an STi (or STi RA, or STi RA Spec C) manifold AND throttle body AND TGV housings and it works with top-feed injectors, PM me to sell it.

If it's the same as on previous EJ series motors, no. The SOHC and DOHC heads have different manifold mounting patterns. SOHC having staggered bolts and DOHC having inline bolts.

Phase I and II don't seem to have anything to do with it. I just bought a 2002 WRX manifold to go onto a 97 EJ25, and it fits no problem.
