88 supra turbo ticking from top end

Well mine ticks the same amount after it warms up. I'm hoping mine is just an unseated valve but please let me know what they say.

It could just be the injectors, they are noisy on toyotas. Even the ones on my 2zzge are like that too. Thats why the ticking gets quicker with more rpm. Alot of people confuse them with valve noise. It could be what you are hearing.

I'm 98% sure it's not the injectors. This is definitely louder than what an injector could do. But I will still check each injector.

If you can't identifiy it by ear then you can always take off the cam covers and check the cam clearances.

I know how to tear it down, but exactly how do I measure the clearances? Thanks for all your help

With a feeler gauge you can measure the gap between the lobe and the shim ontop of the bucket that sits over the valve stem. Here is the link to the TSRM.
