Porting

So this is my first time porting and TBH I really don’t wanna get SUPER into it but I wanna give it a shot, I wanna start off by asking, if I just widen the ports will that effect the power and by how much? Also do I need to know port timings to do so?

I did get all my port timings but idk how to use that to determine how much I should raise/lower ports as well if I did it right. so if anyone has a long rod could you tell me your port timings, so I have a rough idea if I’m ballpark or not with my degrees?
