Default FBody LT1 Compression Ratio

Hey, I know the compression ratio is 10.4:1 or 10.5:1.

I am having trouble calculating this using a calculator however(online)
Bore 4.00
Stroke 3.48
I am Zero'ing the Deck Height.
The Cylinder head volume is 54CC
Whats the head gasket thickness?

I am trying to determine how much .001" of an inch will effect the compression ratio.

I keep getting 12.XX:1 compression w/ those calculations (I am assuming head gasket is .054).
