Default couple questions/issues

ill try and keep it short but i have a few concerns/questions.

first, I made the terrible mistake of putting full synthetic oil in my bike, not an issue if you use motorcycle oil, i didnt, the clutch got soft after a few hundred miles (left if in on advice from my local mc shop, bad idea) and changed it out with rotella, clutch firmed back up, no problems but i did notice a small oil leak coming from the head, real small leak, after 500 miles it finally made a bead from the head to the block, do i need to worry about this? can I or should I switch back to conventional? leave the tiny leak or change the head gasket?

next topic, I had a rattle while the bike was cold and a faint buzzing noise pretty much all the time, most notable while going slow, diagnosed as cct, bought an ape and installed it today, followed the guide on this forum, left it backed out and turned it in until the rattle stopped +1/2 turn and tightened it down, sound gone, my worry is that its too tight, how can i tell? seems like it runs fine but its one of those things thats in the back of my mind.

last topic with a pic, while changing the cct i noticed my front wheel is bent, got the bike about 3 months ago and i guess i just never noticed, its not too severe, no vibration or wobble, take a look, is it bad? can i straighten it? its only on the one side. Thanks in advance guys.

its happens in every gear, most notably in 2nd and up, its quieter in first gear but still there, my bike has 28k on it now so maybe i should adjust the valves? would they cause a buzz noise? it does not happen in neutral, it also goes away as soon as im off the throttle

finally was able to ride again and did some testing, seems the buzzing will go away when I pull in the clutch, ill hold the revs and pull the clutch and the noise goes away, does the clutch make noise normally? tranny issue? i first thought valves but doesnt make any sense now, any advice is appreciated, thanks.

I've tried straightening a wheel like that in my garage with what ever Hill Billy engineering I could think up and nothing would work. Any attempt to bent it back had pressure on the other side that wasnt bent. You understand what I'm trying to say. Even beating it with a hammer wouldnt work. It takes professionals to fix something like that and it still be safe if you ask me.
