Is there any way to repair scratched heatsink heads? Would sanding the top and adding high temp spray of the same color as the head work? One of my motor's head looks bad after a road rash.

what motor you got? I believe you can go buy a new one at tower for like 30 bucks!

OS RG, they go from $50-65 on Tower.

i would leave it. a scratched head wil cool your engine more.
this will be due to the scratches and indentations giving it a bigger surface area to volume. LOL

if you sand aluminum, it never gets smooth unless you have the proper stuff. sand paper dont work.
if you try to paint it with some high temp stuff, it will never match since the aluminum isnt painted it almost like a dye on it.

if you cant afford a new one, and its really only a cosmetic thing id say just drive with it like that. it wont hurt anything.

put some tie wraps on the head next time to help revent this in the future.

where would the tie wraps grip on to? the botom of the head is bolted down.???

the four holes on top that are there for the allen screws. put zip ties through, and bring them though the fin!

painting the head will not help cooling so i wouldnt do it

If you're worried about the aesthetics of it, just sand it with some very fine grit sandpaper, and polish it with a dremel and a polishing wheel and some compound. :sunsmiley
