Okay, now that I have all of my other measurements what is the CC measurement on stock 2.0 heads? Idk if it matters but it is a 74' 914 2.0

It can vary. Mine are 57.2cc. But there is no telling how far they have been decked.

Yeah... That is why I am curious about stock measurements. I know they could vary a little but I just need a ballpark for now... I will take actuals later.

Thanks

if you have every factory measurement but the cylinder head cc and know the stock compression you can just calculate it.. you do not need to know it.. if your missing 2 parts to an equation then your solution would be quantitative ...( did they use cylinder heads gaskets from factory? how thick?)

if your doing a build and trying to calculate backwards from intended factory, screw it and get the heads cc'd.. each cylinder depending on the cut could end up very slight but different 55.1,55.1,55.3,55.2 ect..
