How does cid make power?

If you ignore your cylinder heads, you’re not using your full potential, and frankly wasting your time.
Correct to a point and only because taking advantage of the best cylinder head is t always an option. Be it rules of the class or wallet thickness, making the max is t on everyone’s list.

The example I can give here is the popular Edelbrock or TF commonly chosen which work well for the power output most seek and there attractive price is nice or did they waste it all by not purchasing a Victor head?

Is the power worth the expense?
That’s a personal choice made and judged by the person owning and building the engine for what there doing.

The old way of thinking was bigger is better. Now through research, all it takes is a good set of heads, a good intake, a good cam, and a good set of headers, and you can have a pretty potent engine.
I disagree because adding a great set of heads to any displacement should be done. The bigger engine is the power winner every time.

Edelbrock, TF or the Victor, no matter what engine size there on, they’ll improve it.
