Stock Mopar Rocker Assembly... Sheeesh!
i have never used anything other then mopars factory rockers... i re use them from the motor, after I rebuild it and never have a problem... if you are on the track looking for every last one thousandth of a second, i'd say they would have to go.. but for what your doing your observations on thier quality, and craftsmanship are mistaken.
put your 200- 600 bux you could spend on rockers and buy a carb and you'll actually improvve your performance.
