calculation
Cylinder volume for stock 73mm A12 engine (be sure to measure as it may not be stock)
1171cc/4 = 292.7 cc
Gasket = 0.041 inch = 1.04 mm
bore of gasket (might be 76 mm)
area = pi * r2 = 3.14 * 76/2 * 76/2
cc of gasket = bore * area = 4.54 cc
Head CCs
Dome CCs
Ah forget it ... just use a calculator http://bing.com/search?q=compression+ratio+calculator
Id expect something around 12:1
