As long as the rockers are stud mount you shouldn't need anything other then the rockers on a SBC. Be a flat tappet, doesn't make any difference on the rockers. Why are you wanting to run them? are you running a lot of high rpms?

yes in off road racing and mud bogging there are a lot of high rpm situations and i dont want all the friction in the valvetrain caused by the old slot style rockers. what would i need to convert the whole valvetrain to hydraulic roller? the cam, lifters, and rockers?
