you do if you want to make big power. the only pistons that work with stock sleeves that have a higher compression ratio than stock are Mahley Gold Series pistons. that work witht eh FRM sleeves H series has. and the hIghest compression they offer are 11.5:1. anyhting after that is not available. making you go to another piston manufaturer and needing to sleeve the block...
so yes yoiur wanting 12.5:1 you need to sleeve .
