im looking at a potentially machining 2 to 2.5mm deep flycuts into my pistons (which have samll flycuts in em already) to accomodate a nice lumpy cam...
anyone have an idea how to tell if this is too deep (thus compromising structural integrity of the piston) without sacrificing a piston and cutting it in half???
any general rules on flycutting i should know about?
rules of thumb for minimum clearance of valve to piston?
