SE 95" piston displacement

anybody know what the piston displacement is on se 95" 9:4-1 flat tops(cast)?
Trying to see what my compression would end up being with .030 head gaskets,
Thanks

If you are asking what the dome volume is it's about -1.5cc

Displacement?
If, indeed, that is your question, then the displacement would be 95/2=47.5.
I suspect you're asking a different question though.
If you're asking about "dome volume", then the answer depends on which piston you have. Assuming it's a flat top, then what DBChoppers said.
To calculate compression though, you'll also need to know cylinder head combustion chamber volume, compressed head gasket thickness, and deck height of the piston.
You can go to Big Boyz site and use their displacement/compression calculator to get a very close approximation.
