I would definitely replace the foam around the squarish tube that supplies
air to the pack. That's the worst place for a foam particle to break off.

An RK05 will spin up and load the heads without a controller. It is a darn
good idea to have a terminator
fitted (otherwise noise on the interface lines can do interesting things,
like cause write glitches, don't ask
how I found that out).
It does need a pack with the slotted hub so that the drive electronics can
tell the drive is up to speed before
it tries to load the heads. But obviously a 12 sector (PDP11) pack will do
for that.
So yes, you can use a PDP11 type of pack to see if the heads will fly even
though the drive is on an RK8/E
