Patriot Performance GM LS Predator Heads

Product images may differ from actual product appearance.

Have you ever wanted to start with a clean sheet of paper and get it exactly right from the beginning? How would you like to learn from your past experience and make something that no one could rival? That's exactly what Patriot has done in the development of their new Predator Heads! Every aspect of this new design is intended to be "best of breed." Patriot analyzed the needs and desires of folks just like you and added our years of experience in developing and manufacturing industry-leading performance heads in creating the Predator. These heads are cast with A355 Aluminum Alloy, developed to be tough and durable for the aerospace industry. We raised the valve cover rail so your aftermarket roller-tip rocker arms fit under the valve covers without a problem. The rocker stand boss areas are thicker to handle the strongest of valve springs. Highly-stressed heads need a great foundation and the Predator's deck is rock-solid at three-quarters of an inch. Add all these features to the precise CNC milling of every critical dimension, and you have a real winner. Of course, the Predators feature Patriot's performance five angle performance valve job and Patriot Gold valve springs. Designed, cast, machined and built in the USA from start to finish, there is no finer LS head.
