Actual compression ratio with 440 with flat top replacement pistons

My stroked 440 has the flat tops right at "0" deck. With Indy EZ heads that have the smallish heart shaped chambers, it has 12.8 to 1 compression. I forget how many cc's they are, but it does have a significant quench area. That's something you will not be able to get with those heavy TRW's .060" down in the hole.
