Converting Hyd Roller Lifters to Solid

Kern Dog said

I'm curious as to what the goal is for this.
I'm admittedly not as versed in engine building as others here but the stock hydraulic roller system seems pretty good. Along with being pretty flexible in the wide range of cam profiles, the stock stuff is pretty cheap.
What is to gain by converting the lifters? I read that some claim a few hundred more rpms of operating range. Aside from racing, what advantage is that?
I'm not being critical, I am just curious about what is the upside of doing this.

Oh I don't plan on doing it. The motor I'm finishing up is just a cruiser and won't even see high rpm. In the hours of cleaning up these used factory lifters, I was just thinking about it and curious if it had been done before. Seems like a pretty easy conversion, provided the lifter can handle the extra load. As an aside, I couldn't believe how tarnished and sticky the internals of these used lifters are.

I'd imagine converting them would provide valvetrain stability at higher rpm and all other advantages of solids over hydraulics. If I ever end up building a hotrodded factory roller motor, I may give it a shot.
