Building engine, cam turned and valves smacked piston. Bad?

[KooK]

Here's the deal, putting my engine back together, new FRPP heads, (new)stock valves, (new)stock springs, (new)stock cams. I was lining the cams up and wasn't careful enough, the cam got away from me, twisted, and smacked a piston.

I'll be doing a leakdown test here in a day or two but until then... How strong are these valves?

They are tiny and somewhat fragile...
A leak down is highly recommended............ as you have planned.

While I got you here, do you know if these valves more likely to bend or crack/fracture?

Have seen both.
