Even though its not the same, my L98 motor went thru 2 rebuilt starters just last year within a couple of weeks of being installed. As soon as the car got hot and I shut it off, it would not start for like an hour after and then when it felt like it, it would start right up. It is a scary feeling to go somewhere and shut it off and then a few minutes later put the key in and nothing. I upgraded to a brand new starter (Advantage I think) and haven't had a problem since. My advice is put in the best that will go in there and not worry about it.
