In pic 1 the valve appears open, if you run it watch the guide to see if it moves
They didn't move that I could see...I think the guides may be ok

I know this is way out in left field but does you shifter rod have heim joints on it? When mine get dry they will chirp / squeak a little while she is running...just sayin'.
You mentioned that you checked the stabilizer, have you tried some lube like a silicone or a dab of grease to eliminate them as a source. If you ride in bad weather or wash the bike a lot, they could be dry and in need of some lube.
Give them a twist by hand and see if the feel loose or dry and gritty.
Not a bad call... I'd pop off the top cover and listen and look... any gaulling of the valve could be seen there also...AND you could have it running. IF the noise IS there on the exhaust valve,,,,,Spray it with a lube and see if it quiets... You may JUST have a top end lube problem...
At Least it is the easier cover to remove than the DREADED back one...:s

I had to look up heim joints...I don't have them on my shifter rod....great thought though...I thought for sure it would be something obscure like that. I'm in the process of taking down the top end. Having a heck of a time getting the shafts out of the rocker support plate....anyone know a trick for this?
Is it necessary to disassemble the rocker assy (take out the shafts and rockers) if everything looks good? No play anywhere....
Could the umbrella valves be causing this somehow? Crank case pressure getting by them causing the sound?
Are you rotating the motor to get the lifters on the base circle before "feeling" by hand to see if everything is tight? With the valve train loaded, it will everything will feel tight.
