Important Installation Notes

Ring gaps, piston-to-wall clearances, and bearing clearances must be checked by the end user prior to final assembly to avoid engine damage.
Verify piston-to-deck and piston-to-valve clearances with your chosen head/gasket/rod setup.
Check for proper oil squirter clearance if applicable and modify as needed.
Always follow ARP and TSP torque specs, and use recommended lubricants during assembly.
