If you either resleave or bore out the clyinder walls will you loose the OIL SQUITTERS ? OR does it depend on how much you bore ??


And what is the angle of the valve releifs relative to the center of the piston ( b series pistons)??

IS it 60 degrees ?? And whats the radius or diameter of the valve reief in the piston ??

I have acess to to a 4 axis CNC milling machine and i was thinking of maching deeper valve reliefs into the piston !! HOW mucher deep do machine shops go into the piston SAFELY !!

 

anyone????
