Don't let it get to you 
They're just different numbers for slightly different aircraft configurations, or aircraft owners.
All of Southwest's jets for example have the H4 suffix (as you mentioned).
A 737-300 would be 737-3H4. A -700 would be -7H4, etc. You should get the idea!
It's basically like a special order number/owner identifier! Make sense?
