Hello , i'm ordering a Vertex top end kit for a 150 sx 2020 with only 45hs , súper clean bike , i bought it a few days ago. 

The kit comes with two rings. Those rings have two Marks , N200 and N.

I know the Marks have to go facing up but which ring goes in top groove ? Or ir doesnt matter the order ? . This is my first time doing a top end, don't want to mess up . 

 

Thanks ! 10002415961000241602.jpg?VersionId=t3JpFsM1JW5GsBH1oJfLg

Thanks , and in RMATV they only have one size top end kit . Vertex top end 57.94mm . They don't have A or B sizes. I'm good with the 57.4mm ? The bike is a low hour 45hs aprox .
