The bolt head is the same. All you need is head space gauges in go and no-go dimensions for both calibers. Tools to change barrels like a barrel vise and or an action wrench, and the right barrel nut wrench. You would probably want to get the splined nuts for ease of removal. You can use the original recoil lug if you want to. And lastly if you are not a person that is mechanically inclined(be honest), get yourself a mentor to help you out.
