Spark plug gap?

What should i gap my plugs to?

I have Aluminum heads, 10.5:1 compression. MSD distributor, wires, and msd tfi blaster coil. I'm using Autolite 3924's. All motor, no boost.

Thanks

I have the same set up, just a little lower compression. I use the same plugs and gap them at .050" to. 054".
