any way you can reduce friction from a performance engine is the way you need to go , roller rockers are far better than standard rockers in reducing friction which reduces heat and wear , to build a blower motor with stock type components is a total waste of time and money,,roller rockers is one of the cheapest forms of making the motor last longer and reduce wear...seems like bad advice from a motor man , this is my opion , that is what a forum is about , everybodys opion on the subject
