Need some help figuring CR

Just stick with the Summit Calc and you'll be close. I use the KB one usually myself as that will do "dynamic". The more info the calc requires, the more accurate it'll be but there's more places to enter bad info.

So this is the problem here, especially with the Summit Calc, it gives me the lowest CR equation out of them all. Gives me an 8.3:1, and when using original cast flats, same compressed head gasket, and losing just a hair of material by resurfacing decks and heads, the CR numbers should be at stock, or even a slight bit higher...and that's going based off of factory CR at 9.5:1...so I'm confused..
