The barrel is straight . The piston is tapered to allow the crown to expand from heat . Use you feeler gauges , turn barrel upside down , slip a gauge and the pistin into the bore . Lightly press the piston down , you will find it offers resistance and won't slip through , that will be your clearane . I think .04mm or .05mm is what you are looking for .
