My early eighties Cam Dynamics catalog shows all Olds cams using a 60700-60755 and a few 60800 part numbers....nothing like what you are asking.

You can measure lobe lift w' pair calipers, measure lobe from to top to bottom then on sides,base circle as example if lobe was 1.300'' tall then subtract base say was 1.000''
would equal .300'' lobe lift then multiply by rocker ratio to get lift @ valve.
