Can you run a02 kia spectra 1.8 dohc with only 9 head bolts?

Running a 2002 Kia Spectra 1.8 DOHC engine with only 9 head bolts is not advisable. The engine is designed to operate with a specific number of head bolts for proper clamping force, which ensures a good seal between the cylinder head and the engine block. Operating the engine with missing head bolts could lead to coolant leaks, loss of compression, overheating, and severe engine damage. It's essential to replace any missing bolts and ensure proper torque specifications are met for safe operation.
