No, you can't clock them...but that would'nt have helped my cause any; not sure what that has to do with much. My concern was a blemish in the aluminum where a bent fin made a few rounds as the inlet curves around the blades. A quick refinishing with some 400grit would make it fine, but I was unsure of tolerence issues and would rather a tigher tolerence, so I just used the cold side of this 'new' 14b.
I was gonna hang onto the housing and use it as desk onrnament at work I think
FWIW, I've never seen a stock 14b hotside look so good. No cracks or anything.

It whistles while it WORKS.
I suck.
