i dont know exactly what rocker ratio is for a roller rocker, but i'd expect it would be around the 1.6 to 1 ratio, same as de/det. the hi lobe of a vvl intake cam is 1.65 rocker ratio, whilst the exhaust hi cam ratio is 1.595. shim clearance you have to account for in a vvl though, although nissan dont in many of their cam lift figures

i'm guessing you do know that tomei,jwt and cat cams do make roller rocker grinds still? i have a question mark over long term wear using vvl cams in a roller. than said, there is a shop in the usa who have just made a roller rocker for a vvl head.
