Interesting. The Corteco/ROL gasket is the thickest, I've got all 3 here, I just mic'd the felpro @ ~.050" @ the printo seals and fire rings/~.046" @ the flat, the corteco @ ~.058"@ the flat and the Victor @ ~.047" @ the flat.
If you get another 2-3 cc's and go with a corteco/rol gasket you can get the SCR down to 9.8:1 or less
