Whoa, dude, I hear ya, 10,000 rpm!
No, 10,000 highway miles is about all you can expect from a solid roller on the street. I got 8,000 miles before I broke one.
dcdoug, those roller rockers with bearings are sure nice, won't help those solid roller lifters live though, THAT is all about the
oil that may or may not be able to get into those tiny little rollers that support the roller lifter.
If everything with valve geometry is good to go then yeah, you shouldn't have to re-adjust more than occasionally. With or without roller lifters. I'm just saying IF something DOES go wrong to change that clearance by much, you will HAMMER those tiny rollers in the lifter in short order.
You could, for instance, break a rocker arm shaft, which will change your clearance a lot. BUT with flat tappets you will be mostly OK until you figure it out. With solid rollers you better figure out real quick, or else. So there's less room for error in the valve train geometry with rollers.
