Does anyone know where I can find any info for an H22a1 rebuild/build?

Basically what the title says, I have an H22a1 that I'm planing to rebuild and am looking for any resources that would help me do it. It's gonna be my first engine rebuild so I want to do everything right from the start. What I have done so far is taken it apart to inspect as it was missing the valve cover and I wanted to check if anything fell inside (but really I just wanted to take it apart). Any help is appreciated 🙏.
