Bad heads on RL02: Worth replacing

So one of my RL02 drives (bought on Ebay years ago) is eating RL02 
packs. Makes tings, then the disks have errors in my other RL02 drive. 
Took a bit to figure out which drive was eating what, but I'm 100% 
certain it's this newer drive.

So pulled the heads. The top one had significant gunk on it, the bottom 
one a bit. Pics below.


With alcohol and lintless swabs I managed to clean both of the heads up.


Then put them back in the drive and mounted a scratch pack. With finger 
on the load/run I let the drive spin up and when I heard tinging I 
immediately spun down. Hopefully I didn't trash my scratch pack.

Top head has gunk, bottom one had a few flecks, but looks pretty ok.
Bottom: (picture didn't upload)

Obviously the head is crashing, any idea why and if it's worth replacing 
the head or should I put this drive out for parts? Yes I cleaned the 
RL02 pack before putting it in.

Never dull.
