Which aluminum rockers to buy

goldmember said

Most valvetrain noise is cam design(assuming hyd cam) not rocker arm type. Stock stamped rockers can run 7500rpm and remain very quiet in operation. For any long term street build I would not be running to an aluminum rocker arm. What is the application?

Spring pressures to maintain 7500 RPM with a stock stamped rocker so the valves don't float would be in the major danger zone. I'm talking punch a hole in the rocker arm dangerous! I thought I was nutzzz. I disagree 100% on your statement of not using aluminum rockers on a street engine. Technology has came a long way since 1922! :D
