freaky frankenmotor early 2.2 - late 2.2 questions

[NotLurking]

1993 Legacy Ej 2.2 phase 1 heads, intake, harness, and ECU on a Phase 2 EJ2.2 block?

 

Hi this may seem like a stupid question, to which I have found no no answer... Presumably because anyone thinking of changing their shortblock would want to go UP in displacement in the process, hence all the 2.2 to 2.5 frankendiscussions...  

 

I have an unusual situation because California emissions require that I use an EJ22 block and pre-94 emissions (OBD 1)  for my Vanagon conversion.

 

I am building an "as new" motor, to last many long years and have purchased a factory Phase 2 Ej22 crate short block and have had the Phase 1 heads rebuilt and a valve job performed to use as a basis.  

 

A 1993 Legacy L donor car and will supply the heads & all the intake & emissions systems as required by CA..

Are there any special considerations to using the phase 1 2.2 heads on the phase 2 block? 

 

 Specifically:

 

I am aware that the compression will go up and that the engine becomes an interference motor.

Have done a test build of the long block, and timing, and everything goes together fine, Intake manifold lines up correctly, etc...  

 

BUT... are there any "special" considerations?? 

 

Phase one, or Phase 2 head gaskets usable?? or modifications to either?

 

Tweaks or other considerations to correct for the higher compression? 

(the motor is self adjusting but, to what limits?)

 

 Thanks!!!
