Overheats in minutes at high idle.
Water pump good ,cleaned all water jackets,removed thermostat ,removed exhaust cover and new gaskets. Good flow through tale tell ( pee hole). Removed head to clean water jackets with new gaskets.
Last thing I can think of is head resurface. Maybe building heat at head from compression leak.
Any input would be appreciated.
