: Can someone explain an angled port and valve mods?

I am thinking about trying to get my Disco to be more powerful. I realize that at a certain point a heavier hammer spring isn't going to increase the power. So what is an angled port or any other valve mods? Helpful links on how to would also be appreciated.
