Unhappy help! What drc src do i have?

Trying to find a working calculator for drc and src to see what gasket thickness I should need, stock or .040. And what is the ideal #s for 93 octane? I have stock block, prc 2.5 ls6 heads milled .015th and eps cam 226/230 112+4 icl of 108. Is there anything else I need to make the calc?
I looked on here and found three threads but no calcs work. thanks

I like the excel file that is stickied in the Advanced Tech section.

For whatever reason, the version in the txt seemed older to me (a few more errors... mainly just some of the references in the equations in the compare DCR were the wrong column) than the zip file in this post:

Use the cometic gasket .040. That is the same cam i have been looking at except on a 111 and advanced 2 degrees on a 109. With an IVC of 41 and 62cc chamber with .040 cometic will put you at 11.15 or so SCR and DCR is around 8.74 to 1 which will be an animal on 93 octane.
