I'm not sure which headgasket you should use or what the ending compression will be but it will bolt up. If you do a search there is probably more info.

Yes. Use the HG that goes to your block.

As far as Phase II EJ22 heads, are you talking about post-1996 heads? Or the actual Phase II EJ22 heads that look exactly like SOHC EJ25 heads on the outside?

In any case they will both bolt right up and the CR will be damn near the same for either one. Be sure to run premium gas with that motor. You might be able to get away with mid grade gas, but I never chanced it.
