Are you 100% certain that you've been able to burp all the air from the system? A circulating air-bubble (large one) can also cause the water pump to stall / cavitate thereby causing the temo of the coolant in the block to spike. Also - a bubble at the thermostat will always cause it to fail to open as the thermostat will not read the temperature of the air in the bubble.
Not certain of the hoses you speak of at the rear of the intake - I've seen and used taps at the rear of the intake to purge air from the system.
Mighty nice of Fran on the FOC repair..
