Three ways that I can think of.The first one listed will be the most accurate.

Pull them and have them measured.

Do a cold cranking compression test and input the numbers in to a compression calculator.Not the most accurate but if you know the head gasket thickness and the size of the valve relief pockets in the pistons it will be more accurate.

If you have the part number of the heads you can probably find the approximate chamber size listed for them.That will be in the ballpark.Probably within 1 or 2 cc's plus or minus.
