Default LQ4 Pistons and valve reliefs?

Do the factory 6.0 pistons have valve reliefs in the piston top? I thought they were just a straight flat top with a dish. Thanks for any help.

The LQ4s that Ive seen have a dish and valve reliefs. L92s have a flat top with a valve relief for the exhaust valve.
