Ordered a new long block for my 95. Prior to installing it and or running it, do I need to stress using break in oil, or any other special procedures?

I would do whatever you're engine manufacturer says to. Some may not warranty it if you don't. Some engines have cams broken in on a dyno, some don't. Some want you to baby the engine for a bit, some want you drive the living crap out of it.

Break in oil is a prudent thing. harm can be done if break in is not done correct. There is little harm in running break in oil twice, if the engine was already broken in . Id err on the side of running break in oil.
Make sure to prime the oil pump. Because this block uses flat tappet lifters you should use a proper break in additive to allow these to seat. Beyond that, I always follow the guidelines I found on this site: https://www.onallcylinders.com/2014/11/13/engine-break-guide-10-tips-help-properly-break-engine/
