I've been running something similar. I forget the brand. You do have to modify the the rocker arms. Remove and use a disc grinder to grind 2-4 mm from the adjuster area or a ball shaped stone on a high speed to form a recess in the same area. Makes for truer valve clearances and way fewer need to make any changes.
