Need To Know My Dcr Please!

I have a 233/239 .598/.603 112+2 lsa cam (I do not know the other specs) and have stock bore/stroke/etc and am adding a set of TEA stg 2 LS6 heads milled to 62.2cc using STOCK .053 MLS gaskets. Cam anyone get me my DCR? My scr is a 10.98. All I have is 91 octane and I want to be at the limit on the DCR/SCR, I will have about a .065 relief for the intake valve in the pistons, THANKS!!
