On this one:
http://www.kb-silvolite.com/calc.php?action=comp
Do you use -2 for piston cc if you have valve reliefs?
And if my ADBC @ .050 is 44.5, then I use 59.5 for the calculator?
63cc heads, .052 gasket (compressed value I assume)
Puts me at 11.2 and 9.2.

OK, got this:
---------
That's were you guys are messing up. Your supposed to figure your IVC at .006" first thing before even going to the sight. For this, you will need your .006" intake duration and your ICL. Take your advertised, for example, it's 294, divide that by 2, then add your ICL, then subtract 180. This will give you your IVC at .006". So 294/2+112-180=79* IVC @ .006". The KB sight says to "add 15" to your .050" to get your IVC at .006", but that dosen't work on our cams. It's all about getting the right info first.
------------
So my IVC is 70, which puts the DCR at 8.1
(278/2+111)-180=70
