well if you do use a cylinder brace dont just hammer it in and call it a day. each set up is diffrent tolerances so think about it long and hard. the right way it to have it installed, bore it hone it build it. because some cylinder braces can put added pressure in the wrong places and cause hot spots and added wear in those places after they heat and expand. if you do machine work after the install or at least have it miced and check for roundness and consistancy no matter where the added pressure is the cylinder will be fresh and round no matter what.
