I have never seen a push rod get bent except when a piston slaps an open valve, and I have not seen it not bend calve stem. Hopefully it did not crater the top of the piston. Check each cylinder closedly for piston damage and any possible debris around piston along cylinder wall and for cylinder scoring, as well as damage to valve seats.

My theory is , the timing was so badly off, that when the piston came up and the plug fired, the wrong valve was trying to open at the wrong time. (and this happened within milliseconds of initial start up) . I only say this, because I'm pretty positive, that no way the pistons hit the valves. If I'm wrong I'm wrong, but I don't think so.

And if you are right, OP saves some money!

My experience has been different - but when I was 16 to 19 years old, my dead used to say I could tear up an anvil with a rubber hammer.....and he was right! I floated valves on more that one ride....

Wow. Ok, so much for these being spin-free motors eh? Definitely keep that in mind. Sorry you had to be the one to figger that out.

As opposed to replacing the valves, might wanna just replace the heads, Clearwater has a fully assembled head for under 300...... not sure how much you are going to end up paying for valves, and head work.... new heads just might work out cheaper.

Are there signs on top of the pistons that the valves hit them? I doubt it. The timing was so bad off that the valves were opening at the wrong time , and compression did the damage. JMO as previously stated.

Ah, it was confusing to tell who was correct in that chatroom.
