Suggestion (even though I took the idea of someone else): couldn't you create some kind of channels in the IHS (like the Nexos HP-Pro...) and then do a direct-on-IHS watercooling?

I hope you understood me

I think you will get better results removing the IHS all together in that case, since creating channels in the IHS is pretty extreme too

I got myself a lappings kit form tweakstore.

1 x 400grid (23 x 28cm)
1 x 600grid (23 x 28cm)
1 x 800grid (23 x 28cm)
1 x 1000grid (23 x 28cm)
1 x 1200grid (23 x 28cm)
1 x 1500grid (23 x 28cm)
2 x 2000grid (14 x 28cm)
2 x 2500grid (14 x 28cm)

With this i think u can get 3 lower then stock.

I know its hard to find anything higher then 600 in DIY shops.
U could try "carroserie werken" as they need very fine paper.

Even for paintjobs on cars and such, they rarely go higher then a 1200-1400 grain.

Perhaps special-paint painters will go the extra mile by using 2xxx grain sandpaper.
