Frankly you shouldn't even use a torque wrench on those jam nuts. Just get them snug, the jam nut tool is strong enough to strip the crap out of the jam nut. You can tell the torque spec by the grunting noise you make tightening it, these guys don't take more than a sharp exhale. If you full on grunt you done made an oopsie and not just in your pants.
I tossed out the idea for that torque unit as I have wondered if that would be decent for getting an idea of how tight my two torque wrenches are.

I went through this. Had to end up replacing a few rockers like 5 years ago. My cylinder 4 exhaust jam nut and screw were seized on the rocker at .012" clearance. I could loosen it but not tighten beyond that. It locked in place so I just left it. Worked fine until cylinder 2 went down.

A lot of people use torque wrenches improperly, I've seen wheel studs broken like that with properly sized wrenches and people just use them wrong. I swore by my 3/8ths torque wrench on Honda locknuts my entire life and never came close to stripping one.

I use a short offset end-wrench to do tighten these kinds of nuts and bolts. Easier to access hard-to-get-into places. Plus, harder to snap bolts and round nut heads.

Side note: I did my first valve adjustment today on my stock 2007 with 65K. I'm sure I'm the first person in there based on how stuck together everything was. My valves were WAY out of adjustment; on about half I could only get the smallest feeler gauge in there (.127).The other half I couldn't get anything through. There was a distinct change in engine sound, and I noticed an occasion metallic rattling noise was gone. This sound only occurred at high RPM; like 6k+. Pretty sure this noise thing isn't placebo. Any idea what that sound was, and is it possible to damage the motor with valves that tight?
Obviously there are abnormal noises that can occur if you really screwed it up, but what you are describing sounds normal.

As for torque wrenches, avoid using it with settings on the lower end of its scale. Use the next size wrench down if the one you are using would need to be set in that range. Doing this will generally avoid using a tool too big for the job.
