Hello im new to the AR my 1st build is a 450. I have a 5.56 lower, will i need to get a 450bcg or will the 5.56bcg work with the 450 bolt? Please any help is greatly appreciated

Yes, they cost a little more but they run really sweet, with easy cleanup. Someone, somewhere always has one on sale. If you have the choice, get the M16 version. They have a little more meat (weight) on them in the rear. More weight makes them easier on the brass. IMHO, avoid BCGs marketed as ultralight or lightweight.
Lest I forget,
