Piston Notcher Pilot - 11/32

The Piston Notcher Pilot - 11/32 from ISKY CAMS is a precision cutting tool engineered for serious engine builders and performance mechanics who need to clear piston crowns during high-compression builds or radical valve overlap configurations. This pilot tool serves as the centering guide for piston notching operations, ensuring accurate bore alignment before cutting begins. Whether you're modifying cylinder heads for compatibility with oversized valves or optimizing combustion chamber geometry on a stroker engine, this tool is essential for achieving professional-grade results without costly machine shop fees.

The 11/32-inch diameter pilot is precisely machined to guide your notching equipment with zero runout, preventing chatter marks and uneven material removal that would compromise piston integrity. ISKY CAMS manufactures this tool to exacting tolerances, allowing it to seat firmly in the bore while your cutting apparatus aligns perfectly with the piston crown. The compact design—measuring 7.1 inches in length with a 1.9-inch overall width—fits easily into confined engine bays and milling setups, while its minimal 0.2-pound weight makes it convenient for repeated setup and removal during multi-piston notching sessions.

This Piston Notcher Pilot works with any small-block or big-block engine featuring 11/32-inch bore geometry, making it universally compatible across Chevy, Ford, Mopar, and other domestic platforms commonly modified for racing or street performance. Technicians performing head gasket matching, installing larger diameter valves, or running extreme cam profiles will find this tool indispensable for safe, repeatable notching. Pair it with your existing notching rig or mill setup to eliminate guesswork and ensure that piston-to-valve clearance meets your specification without removing excess material.
