What seals need to be replaced? (never started engine, torn back down)

What seals need to be replaced? (never started engine, torn back down)
Ok so here is the situation. S5 TII engine, S4 internals that I rebuilt several months ago.
Pressure tested the cooling system (with air, used 1 psi and a pineapple racing tester). Found that I had a leaking coolant seal (could hear air coming out of the intake port).
Tore the engine back down, found 2 coolant seals that got pinched and require replacement.
Now here is my question, this engine had never been started with the new parts so I am wondering what I have to replace and what I can get away with.
I am thinking I need:
Water seal kit (inners and outers)
front cover gasket
teflon o-ring front cover
front cover o-ring
Is there anything else I am missing? Also the apex seals seated into position and the break away portion has done so on all of the seals. I am assuming I can just position them properly when I am piecing it back together again?
Thanks!

As for the apex seal pieces, you can either take the seals out, clean them up, and re-glue them with CA/super glue.... or you can just position them correctly when you put it back together. up to you.

Mazda OEM seals come super glued together from the factory for installation ease.. and yeah. as soon as the engine cranks, they break free and what little super-glue burns away.
