identifying 5l head gasket?

[luxbro1]

G'day, I'm wondering if there is a way of identifying which of the 3 head gaskets I need for 99 5l engine. I know it's stamped on the gasket but I'm still driving the car,just want to order the parts so I can put a new head on over the weekend. Any ideas folks?

Problem solved, apart from letters stamped they can have a notch representing the letter, didn't occur that at rear left corner the gasket protrudes to expose that notch(or right rear corner for F gasket). You little ripper, it's D gasket. Note B and C notch are side by side, B will be the closest to the corner. The D notch lines up with the earth wire that's attached to block.
