Thanks Herb - will send to my mechanic and see what he thinks. It seems like there are a few different recommendations out there eg. Continental suggests varying the power between 65 - 75 % every 15-30 mins, only in the second hour. I have attached one of the documents they sent.
Also attached an image of the engine hung on the mount. I asked again re the NDT on the mount - answer was: dye for the welds, x-ray for everything else, and ultrasound if there is surface corrosion to see how deep the corrosion is. If it is less than 10 % - no problem - it just gets resurfaced-mine had a small patch of it, luckily < 10%, so that it what they did, then powder coated the mount.
Also had the rear prop O/H'd as was getting the engine replaced - I didn't realized but it makes total sense that they performed NDT on the prop also.
