'cuz the material for a roller cam can't be the same cast iron used for FT cams.... it won't survive with the rollers' very high and concentrated contact pressures. So that eliminates a cast-in iron gear on the cam that is compatible with the stock shaft gear.Why not just make the roller cams to install and use a normal gear.
Sounds like the softer gear, compatible with the stock gear, is an option in some cases. Some info here:
