Can anyone tell me about these R2/ R5 markings? I have a B18B1 and when i had the valve cover off i noticed them... i tried google and it brought up TSX cams.. but since the TSX is a K series motor, I dont think these cams are them. I also dont know if this is a stock valvetrain... Can someone tell me anything they notice?

 

bump, anyone?

 

Well I dont have any LS cams any more but I can check later on, or google is helpful. But off the top of my head I think those are stock cams.

 

when i searched google for R2 R5 markings, it brought up TSX articles. thats why i posted here, maybe someone could shed some light on it.
