Why did you change these? Failure? Preference?

I am in the motor making it a "103, Lozano Brothers head work, Superetrapp 2:1 exhaust, HPI reworked throttle body, Woods lifters, etc. As long as I was in it, I thought it prudent to replace a relatively inexpensive wear item so I could go a little longer before I had to get into the cam case again. (actually I HATE removing and installing exhaust's!) There was minimal wear to the shoes, they could have gone a lot longer, but as I said, now with new ones I can go that much longer. Wanted to get a look at the oil pump also - it is fine.
I did the Andrews 54 cams, the SE cam plate, GMR adjustable pushrods, and TTS last summer. The tensioners were fine, and the runout was .002. Had my fingers crossed this time, and the runout is still .002!
Sorry to ramble, to answer your question - I replaced them because I was in the cam chest anyway...
