Unless you get really MODERN roller lifters with pressure feed oiling a standard roller lifter will not last long and is NOT recommended for street use. Standard flat tappet cam is always cheaper and unless your looking for max horse power at HIGH rpm is more than adequate.
Some folks like the hydraulic roller lifter tappets because they DO get pressure fed
oil to the lifters roller. So they last much longer than standard solid rollers.
I had a solid roller, it went within a few thousand miles. I replaced it with a flat tappet cam to reduce max rpm, make the engine live longer and STILL provide plenty horse power at a nice price.
Roller cam profiles generally require pretty high valve spring pressures, not neccessarily a good thing.
