25ft lbs isnt going to hurt anything but the thing is a torque wrench is the most accurate in the middle of its adjustment range so when its at the very bottom or the very top of its range it will not be "dead on" as much as it would be in the very middle. I still think you will be fine if its a good brand and in good condition.

Not trying to sound like a wise-***, but when was the last time you had your torque wrench certified? When you put it away, do you back it off to 0, first? If I'm not mistaken, the most common cause for rocker arm failure, is over torquing during installation. As everyone else said, I'm sure 3 lb/ft of torque isn't going to make or break your installation, as long as you KNOW your particular wrench isn't giving you stupid bad readings. It won't hurt anything to have it certified once or twice each year, depending on how often you use it, especially near 0, or close to its maximum rating. You might be surprised at how it checks out.
Although I haven't made a living at it for years, I was trained (trade school) as a machinist. One thing instructors constantly hammered into our heads, was to make damn sure your micrometers, verniers, depth gauges, bore gauges, etc., were REGULARLY checked against a known, accurate standard. I don't see torque wrenches any differently.
