not sure if this is the right section to post but...

12v cummins p pump. i bent 6 push rods in my motor 1 of them it bent it like a s the other 5 it bent up at were the cup is for the rocker arm to sit in. pulled the head and dont see were the vavle hit the piston but when the motor is running it sounds bad like rods i put new push rods in it befor i pulled the head and still sounds bad.. what do you guys think..

its in my 63 nova 12v 1st gen motor with a 215 p pump made 3 passes on the third pass bout half track kinda laid over like maybe de fueling and the timing sliped from 25 deg to 4 deg .

any ideas
 
Are your springs coil binding? What kinda springs and cam?
 
You sure you set the valves right? Maybe the engine wasn't a TDC and you set them to tight. Sounds stupid but cover the easy stuff first.
