From the gapless ring manufaturer of course .
I though you alls were Mechanics and this is basic stuff , used in all High Dollar air craft and Automobile engine assembly and breakin .
If you don't know that';s fine but slamming the correct advice without even botheing to check up on it , is remiss on your part .
Hundres of engines built by me, not one failure yet .
C.A.R.T.Racing engines , Hondas million dollar engines ,Bell Textron / Lycoming Aircraft , BMW , Mercedes on and on....
Really guys .

Not sure where you got your info on gapless ring break-in, but it is very bad advice, and you shouldn't be giving on a public forum. That is how many urban legends are created and usually end up with people causing damage to their engines.
