yes, the elbow will be T'd to heater inlet too then down to the bottom hose (pre pump)Heater return will pipe into water pump cover. Its a bit trial and error but I need to see how it goes before I commit to the efi manifold and ecu. At worst it'll mean a head gasket swap for a non modified one

Sorry Tony, to keep harping on about this, but I am unconvinced by this set up....
you are going to have hot coolant going back to the water pump all the time.
Yes Ian, I can maybe use the T to send it down the new pipe to the top hose as an alternative.
Yes, this is how the heater works, but it has a small capacity, a lot smaller than what you are intending.
Another small point, you would be better plumbing the bypass straight to the heater and having a Tee off to take the coolant
when the heater is closed.
This is what I meant when saying about the T piece. The smaller bore(s) of the heater pipe will have more restriction so flow through the main hoses should dominate
A remote thermostat would alleviate my concerns but obviously that would mean making a new transfer plate.
If I went this way, I would have a separate hose tail for the heater input.
For your configuration, Car builder solutions do a suitable remote thermostat with 32mm spouts, part no. BYST87?

Having said all of this, I still remain unconvinced that it is a good idea to alter the path of the coolant within the engine.
I'm open to opinions and appreciate inputs whether good or bad. Im so far down the road with it now I'll try it out and measure block temps with K type thermocouples stuck to the block under the inlet manifold, and ex side if I can.
I did think about the external stat arrangement, but having less pipes is appealing to me but i wont rule it out
Cheers
