Been looking through cam specs and through all the spec sheets on various cams none mention the desired compression ratio.

I completely understand the valve clearance etc but how do you decide what compression ratio is needed vs the cam choice as looking through threads ive seen a couple where compression ratio was to high or to low

i.e for say a cat cam 110 they give the info

camshaft data:
lash ramp : hydro hydro
duration @ 0.1mm : 282° 275°
duration @ 1.0mm : 246° 239°
valve lift : 11.50mm 11.50mm
cam lift : 
lobe angle : 108° 108°
timing @ 1.0mm : 15° / 51° 48° / 11°
valve lift @ TDC : 2.95mm 2.45mm
