been looking at this job as well and seems like the real pain in the neck is getting the shims out with the cam in.

of course at this point it would be tempting to go ahead and pull the whole head off and take a look. ugh

thanks for the vids @mtbtim , gave me the confidence to buy a beat up old 3rd gen that needs some love at 255k miles
Be careful. Pulling the head off means you need to re-seal /re-do the head gasket properly, and Lord knows being as OCD as we enthusiasts are, you might just get an idea to re-do your block and head while she's all apart. What started as a valve clearance check turns into a F1 race-car engine build on the old lady

My 4Runner had about 208, 400 miles when the job got done. The mechanic said he has seen many higher mileage 3.4L engines not needing adjustment.

At least the feeler gauges with the angle...?
