I just love the solid roller ramp rates, area under the curve and increased lift with no increase in duration. It's really a win win. Is it a pain? Maybe. Does it cost a lot more? Yup. But have to make sacrifices somewhere. Besides, nothing cooler than a solid roller street motor. Of course there's just no reason not to run solid these days. Unless you're a guy who just doesn't like to look at his engine. The myths behind solid cam's needs to die. I know lots of guys running flat and roller solids and they check their lash every 3 months and it's almost always the same. Cam's are different these days. Learn to work on your car.
As for valve sizes? I wasn't going to touch that one. I've been telling people for over a decade that the whole valve too big thing needs to go out the window along with its cousin"3/4 race" cam and "solids are too much maintenance".
