When you talkin about the heads are milled to 64cc , which are stock for LS2 which is what i have , I know by going to 59CC i will raise my compression ratio , but what im wonder is How many thousands is the difference between 59cc heads and 64cc ? what does 1 cc = ? is there a math mathical term for this ?

The general rule is .006 milled equals 1cc. So to reach your target of 59cc you need to reduce the chamber 5cc or .030 milling of the head surface.

so when they say -1cc flat top piston what does that mean ?

That means that the top of the piston has 1 cubic centimeter of material removed from it.
