Here' pics of piston. Forged TRW 2332P 030 (.030 over and 8cc valve reliefs)
Unmilled block and unmilled X heads(70 cc comb chamber)
My understanding (limited) is that a bone stock unmilled open chamber head(like mine) will have negligible effect on quench.
Theoretically here' #'s
0.080" Quench area "depth" + hg thickness (let's say felpro) 0.038"
Gives us 0.118"
Now cuz piston is proud of the deck(0.034"), you subtract that dimension from 0.118"
So 0.118- 0.034" = 0.084".
From what I've read, depending on a LOT of other factors, the "ideal" quench I'm looking for is 0.035-0.050" My 0.084 is a TON away from 0.050. My understanding is in my situation to attain 0.035-0.050 I could....
1. Mill head to block mounting surface (either block or head??)
2. Thinner head gasket
3. Increased piston compression height (new pistons)
I thought I was getting a grasp on it lol then when my math gave me 0.084 I'm starting to question my sanity.
Thanks all.

How could it be a non factor unless there is none?
Take some clay and soften it up in your hands to place on the piston top. Install the head gasket and cylinder head and tighten and torque to spec. Remove, measure the clay. Take this measurement against minimum piston to head distance spec.
Do you have pictures of the piston and it installed at top dead center? Is the head chamber stock? Has the head been milled?
