my brother inlaw and I were arguing if my y7 with y8 head had more than 9-1. So I tried to use the online compression calculator and it won't work on my phone and I do not have access to a computer so I was wondering if any one could help me out and do the test for me.
My set up
Y7
Y7 pistons
Y8 head
Y7 valvetrain (I don't believe that matters)
Y8 hg
Nothing is shaved or anythin its all stock so plz don't flame me just need a lil help
Thanks for who ever helps me out.

What's the OEM D16Y8 headgasket compressed height? You can read in forums that it is 0.027" and you can also read that it is 0.037" like the Z6 gasket. BUT if you know the D16y8 engine has 9.6:1 compression ratio. That equals to 0.037" headgasket in the compression calculator whit Y8 head and pistons. So...what you think?
I bought for my project OEM D16Y8 headgasket but now i think that Z6 or Y8....no matter...
