Well, if it were me, if the valve isn't bent then I'd just chalk it up to the spring being, maybe, damaged a little bit during installation and it shortened its life span somehow. I'd just replace the pushrod and replace that one spring with the same type as the others (probably single -- and don't be fooled by the damper inside the spring that looks like a second spring). I think the Comp numbers for that spring are 981-16, but maybe you have dual springs in there. But, regardless, you have to measure them to make sure they fit. A step up from the "only fix what is broke" method is to replace all 16, which is a PITA when the heads are still on there.
