Yup, considered the "flat type". Used mostly on older model engines. Once you get the correct diameter plug, you coat it in sealer, then you install it into the block or head with the concave side inward. You then place the peen end of a ball peen hammer against the center of the dome and then smack the hammer with another hammer to flatten out the plug slightly. The diameter expands just enough to seal off the opening to keep the coolant inside.still looks like a freeze plug to me.
