Over the counter forged piston at 10lbs of boost?

I am getting ready to put together a 400 with a non intercooled 6-71 for my '33 Ford. My other blown Pontiac has a set of custom pistons with a thick top ring land. If I use the forged pistons that come with the Summit kit, will they live at 10#s of boost at 9.0:1 with an aluminum head?

Thanks, -Abone.
