Default Ticking noise from engine

Started this morning, did my first valve adjustment a couple weeks ago. Tightened everything to spec and had a space of .8mm intake and .10mm exhaust. Cars not a daily driver, no known problems before this. I have stuff for a AP2 valve upgrade, but I'm Supposed to be going to Tail of the Dragon tonight, may have to wait till tomorrow... Did I f**k up myThoughts?

Those specs are incorrect, equivalent of .003 and .004.

Perhaps you posted incorrectly?

0.1mm exhaust barely has any clearance in between, you should have a cel for that. They should be 0.009 and 0.011inch on intake and exhaust side respectively or 0.012 on exhaust valves as billman suggested if you have an ap2v2
