Bent valve in a 360

The other pistons and valves are fine?

Are the heads fresh?

I'm guessing the valve seized up in the guide. Either guides are too tight or something similar.

Heads are fresh, Fresh fuel, #5 piston. Valve springs seem soft to me. I don't know how strong they should be but I can compress them with my hand. The heads came with the valve springs and I had a shop inspect and assemble. My cam has a .540 lift. Everything else is fine in the heads.
