Pushrods

You really need to find out why you are bending the push rods. I have a 225 engine with large valves, head milled .125, a .525 lift cam, single spring with damper, stock push rods, and rocker arm/shaft. Haven't had any problems. Did have to set the spring height, and check for coil bind (close, but just barely OK), did have to shorten the valve guides.
