I made it myself, thats my boat on the sides

I have nailed down the problem, I think

The local 460 Guru talked me thru a process of elimination reason the the correct length push rods seemed to be too short. 10 of my rockers are worn out. My guess is they wore out, the previous owner swapped for the longer push rods to try and compensate, he bent a rod and sold the engine to me...
