Then this bolt must be only about 3/8 inch showing after you grind off the head (maybe a bit more with the gasket).

Pete's idea of just grind it off sounds like something I would do

After I applied a little heat and vice grips but not too much heat

I did not fill every header fastener position with a bolt either

No it is ont he exhaust manifold.. I used the wrong terminology for it.. sorry
