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. a 4” bore would need 0.0012” 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.
