"Without tearing the engine apart" I personally would not recommend anything, other than opening the top ring gap to about .025-.035, but that requires a complete teardown, wich you do not want to do, but my predictions indicate that your engine
will perform a "self mod" of tearing the top ringland of one or more pistions when the
added heat from the extra power expands the ring to the point the gap completely closes and locks the piston at TDC on the down stroke, breaking the top ringland off the piston.
