My opinion is that your decision must not depend on us, but on actual "measured" compression. A slow turning (even if it is cranking 2300) engine requires spark advance evaluation and spark knock assessment to get it dialed so it is at the edge of knock under full load. People have taken off .100" and made it work. Core shift and production variability could hit water jacket at that cut on some heads. Has it been trued before? how does one accurately determine the depth it has been cut to date. CCing the chambers is a start, then looking at piston clearance to the Chamber edge. Some grinding is probable. Valve to piston clearance is to be considered, especially if modified rocker ratios are used, or a custom cam. Pump gas includes 93 R+M ethanol premium. Good luck. Remember it has 3 main bearings. Jim
