I'm going to start rebuilding my block in about a month since my rings are bad.

The head was rebuilt a few months ago to fix a problem with a couple stem seals.

Since I'm using all OEM parts, my question is.....

Should I go with JDM ITR pistons (81.25mm)? Is it worth the few extra bucks? (Planning on letting the machine shop put the block back together)

Just looking for a little umph....

 

If you'll be staying naturally aspirated, I'd recommend using b16 pistons (either pr3 or p30). You'll get a bit more compression and you won't have to modify your stock rods.
