Im getting some new 215cc Pro Topline Aluminum heads , my question is should i go with steel or aluminum roller rockers? im probley going to keep my F303 cam, so is it bad to run 1.7 or 1.72's, e.i. will they break?
comp cams pro mag. rockers are one of the best on the markert,if not the best.they are lightened at the valve and made stronger in high stress areas.only thing better would be a shaft rocker setup
