Final Engine Compression Ratio?

after some setback and delays went ahead and did some checks, I originally found a thread on here with cylinder info volume but can't find it now. - here's where things ended up, with online calculators I come up with around 10.8 on static and 8.4 on dynamic. Curious where this engine will end up with the 292 cam with 247/254 duration and 508 lift performance wise now

info and details:

TRW 11.5.1 dome pistons, unsure if they were milled as has been referenced based on cc value and what I have read on here Im gonna say yes
X-heads - measured volume 68.5 ( this was average - none at 68 and none at 69)
piston 1" down - 205cc's - (+/- about 1 cc)
stroke - stock
Bore - 4.030
Head gasket bore 4.180
head gasket thickness - specs say .049 - .054 - I measure the inner rind and got .054
deck clearance - .01 - this is a bit of a guess but I just don't know and with two different sets of heads everything still aligns well
IVC @ 50 with the cam degreed in @ 106.5 centerline.
