Specs At A Glance

Good To Know

Q: Will these gaskets fit if my cylinder has been bored oversize? A: Gaskets seal the mating surfaces rather than the bore itself, so kits generally still fit after a modest overbore. Check the specific gasket profile against your cylinder before assembly.

Q: Do I need to torque the head in a specific pattern after installing this set? A: Yes, always follow the factory torque sequence and spec for the 550 engine to avoid leaks and warping. Recheck torque after the first heat cycle.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
