All of it to figure compression. Deck clearance, piston head cc, chamber cc and which gasket you plan to use. If you don't know deck clearance, piston compression height and piston head cc will do, along with head cc.
Can't tell you what I don't know. This is my " first time " I can say this " Tech said .050 Gasket thickness and said that would give a head chamber of .078 cc. Piston CC I am clueless. The others I am clueless. That's why I came in here . For guidance.
