What's up everyone?

I'm new here so bare with me. I just bought a 1991 Integra GS with a b18a1. The body for the most part is good and the engine and trany feel solid. For $500 I couldnt say no. My question is, is this engine worth moding? I don't plan to go crazy, but I didn't know if it is worth it at all. I'm working on a budget so I doing the best I can with what I have.

Thanks,
