Rocker arm questions

With spring pressures and lifts get that high does it shorten the life of the Roller rockers? Also to just in the rockers how much HP is expected to be gained if any? Also on a street driven motor are alum rockers up to the wear and tear of street driving? The OP inquired about mine and i mentioned the roller would be better. So basically we are wondering the same thing lol. I didnt think they were best for his build which is why I told him to post a thread. I know they would work but maybe not the best for his application.
