Are CNC-Ported Cylinder Heads Worth the Money?

Topping your engine with a set of aftermarket cylinder heads is a near-certain method for making more horsepower and torque—but is the extra power really worth the money? In this episode of Engine Masters presented by AMSOIL, we answer that question for people who are running a typical street-cruising small-block Chevy V8. We start with a very common, 440horsepower, 383ci stroker engine using production Chevy Vortec iron cylinder heads and swap them out for a set of CNC-ported aluminum heads. Naturally, they make more power at nearly every single point in the power curve, so you’ll have to watch the video and see the full graph to decide if this is an upgrade that’s worth it for you.
