Im porting my 036PRO, first time,so im pretty nervous,good running saw dont want to make a mistake! i want to port it 60% of the piston diameter,my question is on the intake side i have to widen each side of the port .051 thou.this will bring my lower ring pin within .100 of the intake port,is this too close??my piston skirts are.100thou.from ports, this is close enough for a first time porter like me??
