Compression ratio vs Porting

NO!

If having more airflow hurts power it's because more fuel wasn't added with it. Too much airflow is like too much oral sex... A great problem to have that none of us are likely to experience.

Remember, an engine is an air pump. Fuel + air go in, torque comes out. Nothing more, nothing less.

More air flow whether from headers, heads, cam, intake etc.. The carb will automatically add more fuel might need to be setup so not to run rich or lean.

Everyone takes things to extremes I'm not saying run W9's on a semi warm/hot 318, I'm talking fully ported 2.02 valve 318 heads or 340/360 or even EQ may or may not lose some bottom end cause of velocity.
