The only way I know how to get accurate compression ratio is to cc the chambers and calculate the piston to deck height as well as add in your bore. Other factors can come into play here though. No need to do a long write up on that since your doing a pretty basic rebuild. Summit racing has a compression calculator that is pretty handy. You need to know what the specs are first though.
