Just depends on what you already have. Case by case basis - you’ll need to measure it all. Gasket height, deck height, chamber volume
I'm running 10.75 compression with zero deck height, flat top pistons, felpro head gasket and 59cc heads.
This website is a great tool in helping to give an accurate ratio providing you know what you've got.

At the moment it's a stock vn 304
All the parts I have so far are in my first post
If u work in a engine machining shop u may as well take it into work and zero deck your block, hone or bore depending on the condition of the bores of course, new rings, cam bearings, rod and main bearings etc do it once and properly
And stroke it
Indeed....even Billy agrees.
Standard vn 304 blocks vary from .025" to .035" deck height. Standard head cc is 63cc
