IF you read the Speed Pro catalog, they list the dish/dome volume, compression height (which tells you if they have been decked or not), etc.
What about those of us without access to a catalog? I searched the internet for the specs on their piston #H602CP40 and could only find what compression would be with a 64 cc head, etc. No dish volume. Based on what I could find, it appeared to be a 16 cc dish (calculated), but when the box came, it indicated 12 cc on the label.
Goto Google and enter "Speed-Pro #H602CP40" and see how many hits you get. Then how much information is actually available. Ed www.edgesz28.com
