the dish is 10cc different. im not going to hold your hand through calculating a compression ratio, but it is what it is wether you buy it or not
For one dynamic calculators are very hit or miss. Two i'm guessing you have never measured it yourself, ie: poured your cylinder heads and actually worked it out on a cam doctor card versus the manufactures card?. Three dynamic compression is half snake water itself, how can you measure something down to one given value when it is dynamic in nature?
Dynamic compression was the be all end all some tuner started pounding his chest about two years ago. The only thing it is really useful for is figuring out your compression limit on pump gas.
What you are failing to see is that piston dished would have NO effect what you are are posting. How would IVC and EVO that cross more suddenly start magically making more power once a dish is added to the piston?
I can see that your "calculated" figures are bullshit because the increasing dynamic ratios do not tread with the overlap values.
