Im getting my JDM ZC block re-built but im planning to change the piston rings and crank bearings. Is there anything else that would be beneficial to change while the block is out? Water Pump? Oil Pump? some more crucial internal parts?

The block is currently in the machine shop right now getting resurfaced (Cylinder walls and the part where the head meets the block is getting re-flattened and the piston heads are getting sandblasted)
I got a z6 Head all ready that I got out from the machine shop last week (re-surfaced and cleaned)

Im looking for a really good sohc vtec setup for my 89 civic si and once I get stage 2 cams in (winter) and valvetrain (Winter) Im gonna get it professionally tuned. But I just want to make it rev high with stock internals but i wanna put new oem parts in there so any help would be greatly appreciated

Thanks
