Cam Install Question

I have light springs to check piston/valve clearance every 10* or so. Can’t remember how much is recommended to be safe.

Running the Dynamic Compr. formulas off Wallace Racing it shows advancing the cam builds more dynamic ratio and dynamic cranking up to about 4* advanced and after that the gains drop off.

If I'm correct this cam has a fairly short 48* overlap. With the installed ICL at 106 it shows 62*ICA with a dynamic compression ratio of 7.31 and dyn. cranking at 140.
With it 4* advanced I get dynamic compression of 7.53 and dyn. cranking at 146.

Are these just numbers? or something to take into consideration. I could lose some top end and not miss it. Are there any other down-sides to advancing it 4*????
