I have blocked off the lower connection.
Do I have a problem?????

Yes, I think you will. The two rear -12 fittings are only there by design of the manifold & having it fit either L or R cylinder head, if anything the rears should only have a small bleed line (-3 ) to preclude air locks-thats all.
With that system if its using a T/Stat , heater & bypass takeoff barb/s should be fitted as close as possible to the manifold side of the T/Stat. Both of these should then return to those two fittings on the pump ( By-pass to the top currently in use & the heater return to the lower one currently blocked off.
In this manner the coolant will flow past the T/Stat bulb while in by-pass mode and cause the T/Stat to open as reqd, plus the heater if operated will also cause coolant to flow thru the whole engine.
The system as you have it now will have unequal cooling due to the heater removing coolant from one cyl head @ rear and the possibility that there will be less circulation in that cyl head due to this.
