The 2025 IMCA Modified Race Series rules are here, and Engine Pro has wasted no time delivering what racers need: a comprehensive head kit built for Chevrolet performance applications. Designed for precision, performance, and compliance, this package is a game-changer for teams preparing for the new season.

At the heart of the kit are EngineQuest CH350I cylinder heads, engineered to meet the exacting standards of the new IMCA regulations. Backing these heads are premium components like Engine Pro Nitro Black or stainless valves, Nitro Black machined valve locks, chromoly steel retainers, and high-performance valve springs. Together, these parts create a durable and reliable valvetrain that’s ready to tackle the rigors of competition. Supporting the assembly are precision 3/8-inch studs, polylocks, and guide plates, ensuring everything stays perfectly aligned.

Engine Pro isn’t stopping there. For LS and LT engine builders, the company has introduced bolt kits for top- and bottom-end assemblies. These kits simplify cam swaps and bottom-end assembly by providing all the essential fasteners in one organized package, saving time and hassle in the garage.

To address cooling challenges, Engine Pro also launched an innovative LS/LT head gasket. This gasket is designed to improve cooling by allowing water and coolant to flow directly into the cylinder heads, ensuring better thermal management during high-stress races.

Engine Pro’s new products take the uncertainty out of preparing for the 2025 IMCA season. With a focus on compliance, reliability, and ease of installation, they’re giving racers the tools they need to perform at their best. This isn’t just a head kit—it’s a complete solution for teams serious about winning.
