Center plug burns better. Better chamber design as well.

Do you mill the top of the cylinder down to the level of old chamber or just mill the bore out and put a pop up in it?
Might be stupid ? But I just trying to learn.

Pretty close. Then set the squish band down into the bore. Dave can show pictures of it
