In the first post it says 93 JDM WRX so it won't have the rocker heads.
Be aware that compression ratio will be as follows:
9.2:1 with 0.58mm original EJ257 gasket 11044AA641 (holes for intake manifold won't line up)
8.9:1 with 1.00mm Cometic gasket
8.6:1 with 1.37mm original EJ25D gasket 11044AA610
