Cm vs mod 2 cam with 1.2 ratio rockers?

So I’m sure this has been discussed many time on here but I haven’t been able to find anything definite on this subject so my question is simple, which would produce more on track power/torque around the 7000-8100 rpm range on About a 1/8th mile track. Running 212 hemi with head shaved .080, block decked .010 and flat top piston is about .007 ITH with a .020 head gasket. .690 bored carb billet rod flywheel all the necessary parts to turn those rpms reliably. Also where about is my compression ratio, ballpark figure, with this head setup?

Personally I would just buy a cam made to run those rpms without adding the ratio to the rockers. Be prepared to need deeper spring pockets with higher lift.
 
Longer intake valve for high lift cam they have .070" longer intake valve's to help relieve coil bind with the 265 cam n 1.3 rocker for .350" total lift... If valve doesn't run into piston on hemi chanted valve's so eyebrowing piston wud be a must.
