Most SBC's have an unused 1/2" NPT tapped port on the RH cylinder head. It's in the same position as the opening for the coolant temperature sender on the LH head. But since it's on the RH side - it is between 6 & 8 rather than 1 & 2.

That should heat up pretty quick and it is on the high pressure side of the system.
