Does anyone know if you put phase II 2.5 sohc engine heads on a phase I ( 1997) 2.2 liter  (using the 2.2 gaskets) will that engine combo work? 
I need to get a buddy out of a jam in his 2002 OBW by building him the most inexpensive engine i can and I dont have any good 2.5 sohc lower ends that I trust as is. 
If the 2.2 phase one wont work will the phase one 2.5 lower end work? 
Thanks
