Okay, I know it's supposed to be metal to metal and these should be machined, but the "boys" who are putting this car back together have been told that gaskets can be used to fix a small leak and have decided to try it since the manifolds are such a bear to take off. So, can anyone tell me where to get a set? I'm ending up with 10 bolt gaskets instead of 16 from parts places. I was told that gaskets for a 390 High Performance would work. Does anyone know if this is true or do you have any other suggestions? Thanks....
