Problems In Big Block Land?? Help

WOW, let me make this as short as possible. Put the big block on the test stand and everything seemed fine, dropped in truck and had a horrible miss/pop went thru everything and finally had to pull the cam and found a flat lobe. Installed a new 292 cam and lifters and had a valve job with new springs installed on the heads. Seemed to run fine, Lots and Lots of power but the valves were starting to tick. Sooooo now to the problem

Went to adjust the valves real quick and found a brok in half pushrod and a hole in the rocker on #5 cylinder.

What causes a pushrod to break, I am almost certain the rocker was not to tight????

Do I just buy a set of roller rockers and a new pushrod and go on with life or is there something I need to check????

Oh ya by the way I cannot find the other half of the pushrod, hopefully just in the valley somewhere I can fish it out

Any Help guys??????
