408ci/TVS2300/LSA heads build

The pistons are not out of the hole a far as I know. I don’t have a dial indicator (or even the short block yet) to measure. I was told that most aftermarket builders keep the pistons flush or even in the hole some. The block wasn't decked either (as far as I know) as it was a new GM block. Cometic makes a .060 gasket but I have ordered the LS9 gasket which I believe is .050. I asked Richard about the .060 and he said they are pleanty strong and I shouldn't have any problems.
I get a 10.44:1cr with .050

So that puts me at about 10.4:1 if the pistons are not out. I have a PM in to the original owner to see if he discussed this with the builder.
So if they are out .010, how do I add that in to the calculator?
How about a .075 gasket

Usually the SCR calculators have a field to input how far down into the hole the pistons are, just make it negative if they are out of the cylinder. I usually use .010 out of the hole for stock blocks.
