Thin head gaskets for 350 availabilty?
I'm wondering if the .028 gaskets or other similar thin gasket available. Also, I'm wondering how I might check these #7 heads I bought to see if they have been milled. Are there dimensions I can measure?

Check out Cometic MLS Head Gaskets they are available in various thickness including .027

They are pricey at $94 each.
I don't know a dimension you can use to check if they have been milled. CC'ing the combustion chambers will give you one of the numbers to calculate the compression ratio.
If you have excel download a compression ratio calculator like the one found on this page: https://www.us.mahle.com/en/motorspo...h-information/

Unfortunately the cheaper .028" are no longer available. As said, measure the chamber. A piece of plexiglass, vaseline and a syringe. I used coloured washer fluid, easier to see.

I was thinking, what if it's obvious that either 1) the heads have been milled, or 2) the heads have not been milled.
What does this do for you? Either way you don't know the combustion chamber volume since the volumes varied due to manufacturing tolerances, so the next step would be to cc the chambers to determine the volume.
