I also like my roller cam because I don't have to rev the p!ss out of the thing to make some power like you do with other forms of power increasers....and for the street I DON'T have to use huge springs to make the cam work as I am NOT going to rev the heck out of it....so for me and my application I LIKE my roller cam on the street. I AM capable of checking the valve lash periodically and I am NOT worried about my distributor gear as I run a dry sump.
Remember too that revving the p!ss out of an engine is expensive. You need good everything from the crank on up. Simply bolting on a set of the latest CNC'ed double throw down super flowed heads can't be done in a vacuum - you better do all the other things to support revving the p!ss out of it.
Then while you're waiting for your small block high powered engine to spool up I will be done/gone.
