I'm still very new to the world of medium format. I used a roll of Kodak Portra 400 on my Mamiya RZ67 but had the ISO camera dial set to 800. When I metered on my light meter, I metered at 400. It wasn't until I finished the roll where I realized the camera was set to 800. When I get it processed, what should I tell them. Do I push? Pull? I still get confused about this stuff.

I assume you set the shutter speed and aperture to your light meter reading, so everything will be fine. Even if you set the exposure to reflect ISO 800 you will be fine, process normal.

Thank you btaylor! I was thinking that. Just wanted to make sure. Technically speaking, does the camera ISO operation just serve as a reminder then, since it didn't affect the film?

The ISO setting on the back is relevant - if you use the camera with a metering finder. That setting can be very helpful if you have a metering finder and you are switching backs in order to use different types of film. The latter versions of the Mamiya 645 - Super, Pro and Pro-Tl - use a similar system.
If you don't have a metering finder on the camera, all that dial does is serve as a reminder.
