I have a few questions regarding porting and polishing heads.

1. Once done, what do the ported & polished areas look like? What will the walls be like? Smooth or will it show the areas that the tool has been over?

2. What exactly is ported & polished? The openings that connect straight to the runners, what about the openings for the valves? And does this mean that oversize valves are needed?

3. What are 3 angle cut valves etc?

And would doing only some of the above and not all give any gains?
