Holley Float Bowl Leaking after rebuild

update:
yes the float cover is warped at the top and bottom, bows inward.

I tried first the cork gasket from Mikes, I put a small amount of Gasket sealer on the float cover, tightened it up, and leaks like crazy. tried cranking it, and leak would slow but not stop.
I did notice that the gasket seemed a little too big and wouldnt lay flat.

So removed it again, it looked pretty bad.

I then took a sheet of cork material, used the old gasket as template and cut one myself, trimmed it so it fit perfect. Cleaned off any sealant. Put it in tightened it up and no leaks.

so thats where I am at. will watch the next few days and see if it holds up.
Now i need to repaint the intake manifold where the gas was leaking on it, as the nice new red paint has come off.
