What should I prepare before installing this top-end kit?

Gather basic hand tools, a torque wrench, and a clean workspace; refer to a service manual for torque specs and timing procedures. Inspect the crankcase and head for damage and measure bore and piston clearances if possible to ensure a proper match.

• Service manual or torque specifications for 152QMI/157QMJ engines.
• Torque wrench, feeler gauges and assembly lube for initial startup.
• Clean workspace and thread sealant for exhaust studs if recommended.
