Most definitely.

its important to make sure the heatsink is 1000% flat. And the shine comes with taking out all the micro valley's and groves.

flat first and formost. then if shiny comes with it that's cool also

the whole point of lapping is to increase the metal to metal contact between the heat sink and the cpu. the smoother both pieces are the better they contact each other and the less thermal goop you need which is good as well.
when you make it rough there is less metal to metal contact now and instead you need to apply a tad more thermal goop which does act as a thermal transfer device and it works but it is nowehre near as good as metal touching metal.

Is this serious? Of course the shinier one is better, i'd like to know the reasoning behind it performing better rough? Is there any?

Heres a little bit of ascii art to illustrate

|__________| <--- Flat HS
|__________| <--- Flat IHS

|__________| <--- Flat HS
|^^^^^^^^| <--- Rough IHS

Now which is making better contact (i know its rubbish ) The shinier the surface the less grooves, the more contact area. The whole point of the likes of AS5 is that is used to FILL the rough micro grooves on HS's and IHS's. You need less of it the better the shine on the HS.

Shiny all the way! Smoother surface = more contact area. Just like a drag car uses slicks, for the same reson.

Well. sorta. Dragster uses slicks for more contact area for traction. CPU cooler with more contact area will make it run cooler.
