.060 is more common with aluminum rods, you may be ok with .050, just make sure you're sure about that .010 in the hole. You did check it with the piston rock figured right?




Piston rock figure? Dt correct me if I'm wrong but the piston being loose in its bore will rock a few thousands so what ever number that is will be divided by two? Let me know if I'm wrong on this. My old engine was zero decked but the piston would rock .004 out of the bore. I'm running GRP aluminum rods and with that engine I used a .065 cometic head gasket.
