Intake Manifold Gaskets

Hey guys still working on this 273 I picked up and have a question about intake manifold gaskets. The heads on this 273 have been milled .075 and the gap I have between the intake manifold and heads is .075. OEM gaskets are .060. I have found on Summit gaskets that are .125 thick (part #5624-125) but I am afraid that will be too thick and possibly give me issues with bolt hole alignment with the intake and heads. Other than loading up with silicone to make up the difference which I don't want to do, any idea of where I could get gaskets in between the .060 and .125? Or any other suggestions? Thanks.
