New Engine on New homebuilt

Hi All,
I'm not there yet, but, I have a new Lycoming O-360 and in the process of
building a homebuilt kit. Lycoming says to break in the engine at full power
and gives procedures on how to do it. The kit needs slow taxi, then fast
taxi, glazing of the brakes. After take off there are procedures to do at
lower power.... I know I'm not the FIRST in this dilemma, so what takes a
preference? If you wait to do the full power to seat the rings, is that ok?
Thanks for any response, I'm at a loss,
david
