Important Installation Notes

Ring gaps, piston-to-wall clearances, and bearing clearances must be checked by the end user before final assembly to prevent engine damage.
Verify piston-to-deck and piston-to-valve clearances with your head/gasket/rod combination.
Blocks utilizing piston oil squirters may require clearancing.
Follow ARP and TSP torque specifications during assembly and use recommended lubricants.

Important: Ring gaps, piston-to-wall clearances, and bearing clearances must be checked by the end user to avoid engine damage.
