Whats the stock piston volume?

I'm trying to figure out what my c/r would be when I get my motor back together and I was just wondering what the volume of the valve reliefs are on the stock pistons. And this is all the info I'm using so if somethings wrong let me know.
4.0 bore
3.48 stroke
.020 deck height
.026 gasket
??? piston volume

I think its -5cc. I could be wrong though, because i've heard everything from -4 to -10. Maybe one of the experts can chime in....
