Is it a uprated cam

Assuming a standard replacement part, you shouldn't have to if they're all in good condition. Checking/adjustment of the eccentrics however would be necessary to account for any changes between old and new cams.

if rockers show signs of being worn which is likely given you are replacing the cam for a reason then you would want to change the rockers, otherwise the cam may not wear in properly

Yes standart cam. I just thinking if my old rocker will make my new cam worn faster or may be the opening of the valve will not uniform because some of the rocker not uniformly worn. Is it?
