Specs At A Glance

Good To Know

Q: Should the head bolts be replaced at the same time? A: Many service manuals recommend inspecting torque-to-yield head bolts and replacing them if they are stretched or corroded. Follow the torque sequence and specification for your FX HO 1100 engine.

Q: Is surface preparation required before installation? A: The head and block mating surfaces should be clean, flat, and free of old gasket material or corrosion. Skipping this step can cause the new gasket to leak.

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