An odd P to V question
An odd P to V question Im wondering if i should worry about clearance here.
LQ4 shortblock
Stock, untouched 823 heads(L99)
226/230 .600.600 114 cam
Im wondering if i will still have enough clearance with .027 gaskets because of the massive dish my pistons have. If my math is correct, that would put me at 10.31:1

There is nothing to measure. .027 gasket is too thin. His quench would be around .020 or so and that is too tight for street. Quench is the distance between piston to head quench area.
look at the pistons. Even though they have a centric dish, the edges are what will be the danger.
Quench = compressed gasket thickness - piston (in/out) of hole position.

Duh! Quench is a bigger issue here. That is the first thing to look at, rest is irrelevant.
You read carefully and you'll see his sig (mild DD setup).
To the OP, yes you could use .040 gasket, then you'll need to measure (LS3 head has big intake valve)
