Got it i beat it back and forth with a rubber mallet a few times and now it goes up and down freely pb blaster and wd40 works wonders lol. I just started it for the first time and its muffler sounds pretty cool

Did you take the valves out and clean them? The seats are probally covered in crud. The stems could use a proper cleaning.
How about spinning them in the guide and making sure the valve isn't bent?

Well i should but i put all the good stuff on my other engine so it would run because the holes where better shape

Kinda cliche, but:

Seriously, though, I called it, I already said it was probably a stuck valve!
