302 casting on a set of 318 heads

And talking about 273 head gaskets, We have had many discussions here and no-one has come up with a steel shim 273 gasket to measure. I don't believe they were that small of a bore size. I had 2 off mine but pitched them. WTF was I thinking?
:wtf::BangHead::BangHead::BangHead:
Mike...still have the ones that came out of my '67 273. What measurement would you like?
