On a six throttle Porsche opening the throttle will really matter to compression numbers. To a 104 motor with a manifold the size of a bathtub, I doubt it will make much difference.

Those numbers tell me you have a problem with your gauge or technique. They also tell me your engine is fine.

Of course the other posibility is you have a cam timing problem and the numbers are real. Basically the numbers are even and that what a compression test looks for. To make quantitative analysis from compression numbers you need to know your gauge and the engine involved more than is available here.
