Back to the original question, The Fel-Pro #1105 is the 0.051" thick, 4.590" bore, 13.7cc performance head gasket. At $74 each I think the Cometic gaskets are a better deal.
For Reference:
The #1009 is 0.039" thick, 4.410" bore, 9.9cc
The Info is from the Felpro gasket catalog:
http://ecatalog.federalmogul.com/digiPub21/Felpro_Performance_and_Sport_Gasket_Catalog/index.htmThe standard ROL#HG31130 is 0.045" thick, 4.505" Bore, 11.8 cc, and cost about $12 each, The ROL Performance/High Temp #HG31130HT is the same size and costs about $22 each from this place I found:

I don't know what the 440 source 0.051" thick head gasket is?
Mr gasket offers the thinner gaskets, thicker copper gaskets, and MLS gaskets, but still in the 0.043" thickness.
I found these that may be what your looking for:
SCE Pro Copper Head Gaskets, 0.062" and various bore sizes are $125 pair from Summit.
or
Flatout Gaskets #900464520 are 0.064" thick, 4.520 diameter, 16.8cc (calculated from bore & thickness), and cost $140/pair from Summit.
Here is a link to summit chrysler big block head gaskets. You can do "show all" on gasket thicknesses. It looks like the SCE gasket have the largest selection of thicker head gaskets?
