Hi JJ,
I am not positive but I do not think you can use roller lifters on a
mechanical or hydrualic cam.  The problem is the profile of the lobes. 
I believe for rollers there has to be a specific lobe profile.  I also
think you must change springs for the rollers to work properly.  Check
this with a cam manufacturer or good engine machinist.
I have had several roller cam engines built for racing and the
adavantage is unquestionable.  However, when I did this all the
components were designed to work with roller lifters.
