Would not be a hybrid if you did not use WRX heads...
Using the S20 heads as is is OK, modifying the chambers to the larger bore would be better...
You have a phase 1 so STI rods will go in without changing things. It's an interference piston so make sure you use a thick enough gasket to get the proper quench.
