I do agree the cam is old tech and the heads are not the best choice either.
I am not a cam guru, intelligent cam designer so I don't have the credentials to argue with you other than I have been building small and big block chevy's at various power levels for over 25 years. All I know is I aint building a 8.0:1 motor for nobody with a 222 @ .050 cam.

I've been doing this for 25yrs myself and always was told to match the can with the compression. Until recently when I didn't talk to a can designer about this exact question. Since you didn't want to play along I'll fill in the blanks. On the compression stroke the camshaft has the valves closed so its not really doing anything for that particular cylinder so if the engine is 8:1 or 13:1 it doesn't matter because the camshaft has nothing to do with that cycle of the engine. You don't can a engine based on compression, you can a engine based on desired rpm range.
