    I've had the stock rockers break on two different stock engines, one was a stock 365 hp 327...if you want to call it "stock"
    If the ones you have are original, you may want to think about new rockers. I currently have the aftermarket stamped steel rockers with the roller tips and they have 48,000 miles on them with Crane cam and springs with no issues.
    Used to Drag race and Crane gold were considered the best full roller rockers and Harland Sharp were run by several friends without issues.

    Remember you'll need to install new valve covers or spacers too if you change to regular roller rockers. The comp cams ones with just the roller tip are usually OK. More $

    Full roller will reduce oil temperature and shear damage to the oil. Roller tip does nothing and if not aligned perfectly, will accelerate valve guide wear.

    Sounds like you have a mostly stock engine. Stamped steel rockers have worked just fine for them for many decades and continue to do so today.
