Roller cam/lifter problem

Inverse flank HR helps on the acceleration/ collapse phenomenon
all conversion HR are made by Johnson AFIK
IDK how Huges sources
Mopar has about the base circle of a BBC and most HR grinds are for a SBC base circle so no problem going to SBC base circle (longer pushrods but you are going to do the geometry drill anyway- right?
Unless you have a roller that was ground for a BBC/ Mopar
Mopar roller can use a bigger wheel (good- less side thrust) but no HR's come that way that I know of (wonder what size my magnum has)
