Default compression help

I found 3.904 pistons with a -32cc dish.I'm trying to find out what the compression ratio would be with stock 806 heads.That would be a stock stroke engine too if that helps.Any help would be appreciated.

Too low. What are you trying to do?

A 32 dish is way too much, the compression would be extremely low.

I guess they're for major boost.They are on ebay and they are custom je pistons w/33cc dish.Just thought I could get them cheap.Sounds like 8.6-9cc is the norm for 347 applications.Thanks for the info.
