        Note: All rings will need to be gaped to suit your bore. As a general rule of thumb piston rings on vintage engines should have 0.003” of end gap per 1” of cylinder bore size (i.e. 3.5” bore would need 0.0105” end gap). Be sure to gap your rings on the smallest or unworn part of your bore, on worn or older engines that have not had a new liner fitted this would normally be towards the bottom.
