What Munster said ^^^
After flying the 737NG (800) for 8-years in a Part 91 PU/121 Supp operation where we as the small group of line pilots did the post-mx acceptance along side our flight mechanic... we always had a maintenance procedure available to us. Our static engine runs were never to 100% N1 though, and we typically brought the opposite engine up to an intermediate thrust setting to reduce side-load. I'd really recommend digging it out of the MX procedures to avoid an embarrassing episode.
