With the engine being aluminum (I'm fairly certain it is, or at least the heads are for sure), just replacing that head gasket wouldn't be the smartest thing in the world to do (aluminum warps rather easily when overheated).
I tried this in my '91 300ZX Turbo when it overheated... Iron block, aluminum heads... heads were warped slightly, but in "spec" per the service manual... still redeveloped a leak after replacing the gaskets... =( To replace the gaskets you really need to have the heads milled and decked... and then runner a thicker head gasket... no fun all the way around.
Why not just drop a VQ35 in it if you're looking to just replace the engine?? Probably run you about the same price as the VQ30 is you do enough searching...
