Who make good soild roller lifters & who make bad

Those are small solid rollers, which was why I asked. You should be fine with the solid body Comp 829s without any odd maintenance. I'd still plan to have them rebuilt at every 8K mile interval, and the springs tested yearly (on the head testers are cheap). You will need to replace the springs, retainers and locks with those Stealth heads and that much cam. For the street, the hydraulic rollers are a good choice with no special maintenance, but I would bush the lifter bores with any roller. Friend has run the Comp street hydraulic roller in his 496 for 8 years now.
