Better get the cams too, if you're gonna take it apart that far. Proper set up and tuning on the dyno should get you close to 200hp at the crank, or 165-170hp on the pavement. Been there, done that. My ZX11D4 was set up with forged arias pistons, Falicon crank and nitrided rods, stock pipes, Keihin FCR 41 flat slide carbs, Muzzy cams, and Sims&Rohm ignition advancer, and this beast was into the mid 9s and dyno'd 169hp at the rear wheel. And it was dead straight and steady doing it.
