They also include plasma-moly file-fit rings, giving you the flexibility to achieve a perfect seal in your cylinders. To top it off, King XP rod and main bearings are included, offering excellent wear resistance and performance.
This is a comprehensive package for anyone looking to build a high-output LT1 engine. Keep in mind that this assembly is not CARB approved and cannot be shipped to California.
