I've bored my Cub .040" over without any issues but not .060". I wouldn't think it would be a problem. I've bored a John Deere B .120" over with no issues.

Ten years ago I bought a power unit 20 newer that my Cub. It had a thrown rod and I paid $100.00 for it. Machine shop bored it 60 over and compression runs in the low 160s. The engine had a plug midblock where I installed a sending unit for a thermostat. At that time the engine ran in the middle of the green running a Woods 59 in mid 90 degree weather. Two summers ago I installed a thermostat and it fit snugly in the coolant outlet. It is a 170 degree thermostat for a Farmall A. Now the gauge needle moves from the bottom of the green almost to middle and then back down. The Cub warms up quickly in the winter for pushing snow and I don't cover the grill anymore. Of course that would be of little concern to you in NC. There are a lot of naysayers concerning this, however it works very well for me,
