Wouldn't the pushrods show some type of bent if the valve touched the pistons? That's the weirdest thing inspecting all the the lobes, pushrods everything looks normal on the cam except what I can't see on the opposite side of timing chain cover.
no.. could bend a little and not bend a pushrod.. no matter what, when you replace the sheared key.. run a compression test on all cyls before starting it.. then you will know for sure.. so far it's not looking too bad though
