I don't know but, I thought the TBI 5.7L with 65cc 193 heads and 12cc dish pistons was closer to 9.5 CR, these 162108 heads are 62cc so CR should be higher, maybe closer to ~9.7?
I didn't look at the shortblock info prior to posting. Looking at it now, they claim 9.7:1 with 64CC chambers, so 62CC may put it closer to 10:1. All that will depend on headgasket selection and how far down the hole the pistons actually are, and actual chamber measurements. If everything specs to nominal, then it will be pretty healthy indeed.
