Hi,
Not my specialty, but the HG should match the block in most cases - for either of your heads.
Running the EJ22T (graphite?) is the easiest, but I'd look into getting a MLS-type for longevity. The phase II/2 EJ222 ('99-'01) might be an option or may be too thin?
Supposedly Cometic can custom-make them if the coolant/oil passages don't line up.

Double-check your DOHC intake manifold (IM) fits those SoHC heads, too.

You'll need some aftermarket injectors for anything over about 300hp, so look on here for best options. Probably pick up a used set in the Classifieds.
