Default 9.5 Dcr?

If I'm off somewhere I can't find it. Here's what I've got.

5.3 w/ stock pistons, approx. 6cc dish.
Pistons are .010 out of the hole.
.045 head gasket.
Heads are approx. 58 cc.
I used a degree wheel and the cam is 226/232 114 lsa. It came w/ 0* ground in so I advanced it 4* and end up w/110 ICL.
I'm using stock #'s for stroke 3.622 and rod length 6.098.
Calculator says 9.5 DCR. Are my #'s off somewhere or am I just getting away w/ this?

Many thanks to jrp for the cam guide.

0.006 0.050 0.200

Now I get it. If I put the duration in at .006 I get 8.13.

Thanks for the help.
