Does this look to be enough clearance? OR too much?

Modifying an oil pickup tube for an early oil pan. I put a straight edge across the pan and measured to the bottom. I made a little go/no go gauge (if you will) and here is where I marked the oil pickup. Before I TIG it, any concerns or adjustments any can see I should make???? I have the bail holding the screen on the pick up just about touching the bottom of the pan?
