I'm looking for opinions. We have a 440 in my wife's duster that is drag race use only. It has the ProMaxx heads. I think they are a copy of a Edelbrock RPM? Either way we have ran the motor for 2 seasons with stock rocker arms and push rods. It has a Launati Voodoo hydraulic flat tappet cam with .533 lift. It ended up bending a pushrod and breaking the adjacent rocker arm at the last race this year. So it's time for an upgrade.

Originally I was thinking of the chromoly comp rockers but the max spring diameter is much less than Harland Sharps. I'm open to anyones thoughts or suggestions.
