I didn't even crack my motor open till 103k & it still had the original cross hatching in the cylinders. It's all gonna depend on how well taken care of your car is. If its in perfect running shape right now, I'd go for it. I'm at 112k now & haven't had a single issue

I busted my engine open at 30k on the dot lol. Your valves are probly a bit burned if its had a hard life, could add a bit of power, just consider all your options and make a very educated descision.
