This vehicle does NOT have hydraulic lifter setup. The valve adjustment is via lock nut.
True

Frankly, 100K is way too early for needing valve adjustment on that engine especially if you had been good to the engine in terms of oil changes.
Did valve adj on my Honda V6. Some exhaust valves had zero clearance just over 105k miles. Oil changes every 5k. So about 100k miles is a good time for Honda V6 valve adjustment which is needed even if the engine is not making noise.

If you really want this to be done, then take it to the dealer and do make sure that the job is actually done. Do they have glass wall where you can actually see the technician working on your car? Otherwise, I can guarantee you that a properly performed valve adjustment at this mileage means you will notice zero difference in the running of the vehicle.
True. Except wall jobs exist at dealer also. If you get misfire codes at 150K, valve adjustment is one of the causes

Conversely, if the technician were to do a "wall job" (google it!) you will never know it
When the Honda dealer replaced my transmission, many fasteners of the plastic parts under the engine and trans were missing. Scrape, clunk, rub were some of the noises I heard. I wonder what else they missed. Wall job, sunshine job, bad job. So much for a good job at the dealer.

OK, I am jaded but if I am going to shell out $400 for labor charges, I need to be 100% sure that the work is done right.
Maybe an indy Honda specialist that will be willing show you you a few minutes when he does the adjustment would be an adequate situation
