stamped steel rocker arm delection

i did go from a 5/16 to a 3/8 chromoly push rod .080 wall,i did do some r&d on the rocker arm with several versions of welded rockers,you can get the rocker to stiffen some but you end up adding so much weight to the valve train it would be counter productive it looks like the bottom of the rocker wants to spread out ,,but if you put a rocker in small tool vise, you can see how it flexes real easy with little turning effort ,,its amazing that how much they flex but the breakage is low gmonde
