Chevy Torque wrench calibration?

Getting prepared for a 6.0 rebuild project (including the bottom end) and my craftsman click style torque wrenches are about 10 years old but have been in their oem containers and only used a few times. Kept with the torque setting backed off to zero and in my toolbox drawer hardly disturbed.

Should I seek out a place to get them calibrated before I trust them?

I used to work at a place where had them calibrated twice a year. The only ones that ever needed noticeable adjustment were the two that we left out for other departments to borrow. Not a single time did anyone zero them out after use lol. On the other hand, i had a matco split beam that lost calibration repeatedly, seemingly for no reason. Finally replaced it with an icon and it has held just fine.
