Well, I'm away for the weekend. I'll try tommorow.
The scratch is very small - about 1 mm long - and is fully covered by the paper washer I used to mount the block. The paper washer is about 2 mm circumfrence, so it's within 1 mm of the screw hole. I saw no visible damage to any of the tracks.
I *HOPE* it works (actually, it's been an ever present thought on my mind all weekend lol.)
But yeah, I don't really want to try to fire it up until after I leak test and I'm not too keen on starting it up with only the copper waterblock...so, I'll know in about 2 days.
I so hope it works
