Brent,
MOST pushrods only fail from geometry mis-alignment. This HAS to be checked before anything!
JEGS,
www.jegs.com has what you need to check the proper length.

Part number is 270-99726
I'm guessing at your motor, so double check my part numbers!
Once you KNOW the proper length, then maybe a new set.
Good luck...
