Picking a good set of Chevy LS cylinder heads is a great way to improve the performance in your Chevy/GM LS engine. It’s no secret that the LS responds well to cylinder head swaps, so finding the best cylinder heads for your LS engine is a big step towards building serious horsepower.

That means you’re in the right place—Summit Racing offers a massive lineup of performance LS engine cylinder heads from some of the best names in the industry, including Trick Flow, Dart, Airflow Research (AFR), Brodix, Mast Motorsports, Edelbrock, and more.

Cathedral, Rectangle & Raised Port LS Cylinder Head Options

Summit Racing carries LS cylinder head options for the early cathedral port (like the LS1 and LS2) head, later rectangular port (the LS3 and LSA) head, and the raised square port (LS7) head designs—check out this handy infographic to see the distinction.

Better still, you’ve got plenty of choices between different intake/exhaust runner volumes, and combustion chamber volumes. That way, you’re able to find the best cylinder head to complement your specific engine setup, whether you’re running a big power NA motor or going the forced induction route with a turbo or supercharger.

Assembled vs. Bare

Most of these LS cylinder heads are sold fully assembled and ready to bolt right on to your LS motor. But you’ll also notice that many manufacturers offer bare cylinder head castings as well. Bare heads are perfect if you want to install your own valvetrain tailored to your exact cam and engine specs, or plan to do extra intensive port/polish work. Better still, bare cylinder head castings are a great way to save money if you’ve already got your valves, springs, rockers, and other valvetrain parts.

Fast, Reliable Shipping

You don’t want to wait on your LS cylinder heads, which is why Summit Racing offers blazing-fast shipping and plenty of tech support before and after you get your heads. So, if you’re ready to find the best cylinder heads for your Chevy/GM LS engine, start shopping now at SummitRacing.com.
