If you do find original intake gaskets, beware. The originals I found were very nice but hard as a rock, so they leaked water into the intake runners. I was pretty meticulous on assembly and torqued to the aluminum intake spec, which I think is 16lbs +/- as I recall. Re-torqued the intake to 22 lbs and they sealed up just fine. Never had an issue with Mr. Gaskets or FelPro which are very compliant compared to the originals when torqued to the 16lbs. Make sure your intake and head surfaces are a good match.
