do i have the wrong headgasket?

Some of the ports a blocked off with the head gaskets.
Don't worry about it.
Use what you have, I do highly recommend spraying the head gaskets with Permatex copper spray gasket, this stuff works, I use it on every head gasket I bolt on.
Apply it as directions tell you too, go ahead and finish bolting the engine together but do not at add antifreeze for 24 hrs.
The heads will not leak.

Use the copper spray it is about $10 a can, and you will have plenty left over to do many more motors.
