ENGINE PRECISION SERVICES

In the world of high-performance internal combustion, machining accuracy isn't just a requirement—it's the foundation of reliability. At Heritage Performance, we understand that tolerances measured in microns determine the difference between a perfect build and catastrophic failure. Our precision machining services ensure your engine operates with maximum mechanical efficiency and longevity.

Block Machining

Cylinder Boring

We utilize precision boring equipment to restore cylinder geometry, correcting taper and out-of-roundness to ensure structural integrity and perfect piston clearance.

Precision Honing

Advanced plateau honing processes create the ideal cross-hatch finish, promoting rapid ring seating and superior oil retention for long-term engine performance.

Block Decking

Surfacing the block deck ensures a perfectly flat mating surface and correct piston-to-deck height, critical for optimized quench and high-compression head gasket sealing.

Align-Honing

We verify and correct the main bearing housing bores to ensure a perfectly straight crankshaft centerline, reducing friction and preventing premature bearing failure.

Head Work & Reconditioning

Maximum cylinder head efficiency is achieved through precision geometry. Our reconditioning services cover multi-angle valve seat cutting, surface resurfacing for perfect gasket sealing, and performance porting where specific flow gains are required. We work to microns to ensure every head that leaves our facility delivers consistent combustion and reliable cooling performance.

Dynamic Precision

ROTATING ASSEMBLY • VIBRATION CONTROL • LONGEVITY • SMOOTH PERFORMANCE •

Engine balancing is critical for performance and longevity. By neutralizing internal forces within the rotating assembly, we eliminate destructive vibrations that lead to premature bearing wear and catastrophic failure. Our process ensures every component works in perfect harmony, delivering unmatched smoothness and reliability even at extreme RPM levels.

Rotating Assembly

Precise weighing and matching of pistons, rods, and crankshaft counterweights to achieve perfect dynamic balance.

Vibration Control

Eliminating harmonics that drain power and compromise engine health, ensuring maximum power delivery to the wheels.

Precision Measurements

TOLERANCE 0.0001"

We utilize temperature-controlled environments and calibrated Mitutoyo micrometers to maintain tolerances as tight as 0.0001 inches. This level of precision is non-negotiable for high-rpm racing engines and performance restorations.

MICRO-SURFACE 8-12 RA

Surface finish is quantified using digital profilometers to ensure Ra (Roughness Average) values match exactly what your piston rings require for proper seating and longevity. We achieve consistency across all cylinders.

CLEARANCE 0.0015"

Main and rod bearing clearances are measured multiple times throughout the process. Our Sunnen bore gauges and digital readouts allow us to verify that every rotating assembly component operates within its ideal oil film window.
