Valve is bent and started kissing the piston...
My question is how bad is this?
Does this affect the motor working running with a piston like this?
How important is a new piston?
What is the likely hood the crank/bottom end is affected if I leave this piston, or even if I replace?

Also, I was able to slide the connecting rods on the crank, back/forth on the crank about 1/8". And I mean all connecting rods to the crank, is this normal?
They are tight up and down, but not back and forth.

I haven't thoroughly done a rebuild, but I expect new heads, and lifters, pushrods, possibly cam, and possible piston? Going to be a new process measuring pushrods...

I think a 351 swap should now take place ha ha. At least that's what I'd do. If I ever get a Fox again that's what I'm def going to do.

Don't want to spend that much... Going to be keeping stock block for now. I'm thinking aluminum heads, comp cam, and just rebuild it back up

Lol I was joking, although you could probably find a decent 351 for cheaper than the cost of heads and cams.

from what I can see I don't think there is any damage to crank or rods. I have seen much worst pistons to valve collisions and the crank and rods were fine. As for the piston it does not look terrible (from where I see it) is this a stock piston? is it forged?, if it is a stock motor with no power adder and you cannot afford or have the time to replace it, run it, but if you can replace it do it for some extra piece of mind.

I would also want to know why your valve hit the piston before I went out and got replacement parts.

If I have to take a guess I would say weak valve spring or over reving (valve float)

Bent valve,
Inspected further, the bearings for connecting rod/crank were smooth and fine, torqued all back down and soon going to start re-assembly soon...
Just debating on what to do about heads...

The bent valve would be a result of the contact with he piston...something had to put it out of time aka a broken spring or something.

Must be from valve float, from being over revved in downshift
