The intake closing is not the same at .006 as .050, is it? I wouldn't think so. I called Comp. Cams cam help number and they couldn't help. The cam in question is the XE 262H for the small block chev.
If you go to KB-silvolite.com, they have a compression calculator. That's the one I use. They will ask you intake closing point... OR... you can add 15 to the .050 ABDC. I would put in the .006 spec that you have, that should be very close to intake closing.
