Mitsubishi part number MD372348 is the same part, but made of aluminium, so once it's installed it will never fail again. I highly recommend swapping out the rubber seal for the aluminium one.
4 vc gaskets later I bought the alum part.. I had to grind at it a bit to fit (there was flashing from when the head was cast.) Has not leaked since going on 1.5 years now. Doing the same on my friends van, just replaced the vc gasket a few months back, its leaking again...very annoying.
