Do not remove the botton ring.

If you do not fit the bottom ring: the land and below the top ring will beak away, and the top ring will not seal against the bore and will gouge the bore.

The making UFO's is not such as easy task as one thinks; the fitment and subsequent jetting will probably create frustration to many users. Its a path not to be taken lightly.

Its much easier to buy and further develop your knowledge and fully understand the amount of the time it will take to get them to work effectively with your engine.
