I found techinspetor1's post and how he came to 44 deg , here is my other question , the program doesnt take other things into effect , like having a sparkplug will change the cc , the head gasket is not round its more oval with the valve reliefs so that must add a cc or 2 and when the to of the bore is notched to unshroud the valve that must be a cc or 2 ?

When I use the KB calculator and go from 113cc head to 118 cc the comp drops down to 9.98:1 , so if the plug and valve reliefs and head gaskets make up a couple cc's wouldnt it be the same ? wouldn't you have to literally fill the head on the block torqued down with gasket and piston at tdc to get the real a real number ? Or cc the head gasket and chamber seperate?
