hard to tell exactly from pic but it looks as if valve is tweaked meaning bent on the stem.if you do not have a weak or broken valve spring then I would pull the spring off and try moving the valve up and down if bent it will never seat.it should be snug due to the guide but if not bent it will move by hand.the problem is that if the spring was broken or weak on start up with idle a little high if using choke the spring will have let the valve hanging and when the piston came up it does not take a lot to bend the valve stem.I have seen it where it hardly leaves a mark on the piston without a very close look.something to look at easy to do without any special tools.

Sooooooo..........ya really think THAT piston might have kissed the valve in this FLATHEAD engine to bend the valve? DD

This is a flathead, the piston can not hit the valve no matter were the valve is.
