Default s&s piston dome volume

Would anyone know the aprox dome volume on a set of S&S flat top pistons that are included in their 106 kit?

Im trying to narrow cam selection using the big boyz head porting calc. I've watched videos on how to measure with alcohol but didn't think it was worth the investment for a 1x build.

Not trying to confuse anyone...
I Was referring to the addition of cc's (+1.5) when using a compression calculating formula.....

Oh, that's right.
The one on-line calculator wants that as a plus number.
I see what you mean.

No sure which calculator you guys are discussing but the BB calculator uses a dome as a positive number and flattop pockets as negative..

I do not use that calculator much if any, and I stand corrected.
Minus numbers, yes.
