Hi gents.just put heater box in and unsure
if bottom hose on heater box goes into the
Top of water neck.
Cheers maz

Doesn't really matter as it won't have any noticeable effect on the thermal efficiency of the heater core.
I would connect the lower hose from the heater core to the nipple on the water pump and the upper hose on the heater core to the nipple on the thermostat housing.

came out till cracked the cap.
Bloody freezing down here..brrrrrrrr!!!

It probably doesn't matter because it's a pressurised closed system but I'd be inclined to connect the 'out' from the water pump to the inlet of the heater that fills the lower part of the heater first, that way as it fills, the water rises pushing the air out via the top.

So water flows out of water neck and into
pump.

Bugger.damn thing is working pretty good.
So water flows out of water neck and into pump.
From the diagram, the arrows indicate flow, it flows into the heater through the bottom hose (yellow) and out of the heater from the top hose (blue), so it goes from the pump to the bottom of heater. Pretty much how I thought it would, as mentioned above.

It doesn't really make much difference as the water circulates through the system rather quickly and if you're that cold you just have to wait till the thermostat opens before you'd notice.

the big job the top outlet hose was routed to
the manifold it just then exits manifold
and back to thermostat.some later models
Exit back of manifold then to heater then
long hose back to bottom inlet on housing.

Why would you have to wait for the thermostat to open? In the following installation diagram that Bazza has kindly posted the heater connections are both upstream of the thermostat.
Therefore the water pump will circulate water through the engine block and head to the heater core and back to the water pump without the thermostat being open.

If you read my comment properly, 'if you're that cold' i.e. icy conditions, the minimal radiant heat from the water pump wouldn't be enough to do its job to warm you up.
When the thermostat opens minutes later, then the real hot water starts flowing.

Heater back in is after id leave my joint
And traveled around 3-4 ks the temp guage
would go off the clock,now it sits on bout
190 which i know is still incorrect reading
But its working better than it was.
Discard oil temp its not earthed out properly
somehow.if i push on fascia she pops up to
about 30psi

You know the funny thing is is before i put Heater back in after id leave my joint And traveled around 3-4 ks the temp gauge would go off the clock,
now it sits on bout 190 which i know is still incorrect reading But its working better than it was.
It makes perfect sense because you added another radiator to your cooling system. The heater is a miniature radiator that sits under your dash, the extra volume in the heater and two hoses, gives you more thermofluid to circulate through the engine.
You will notice it will cool even better if you switch the heater fan on, which will blow air through the heater, cooling your engine even more - may not be comfortable on a hot day though, lol

Radiant heat from the water pump? The water pump will be circulating the coolant that is quickly heating up in the engine through the heater core well before the thermostat opens.

You're right, my mistake. Thinking of a different system. It is Friday night after drinks, hahaha.

as water bypasses the thermostat.
Wonder if putting the hoses to manifold
back on will help.she idles very low and
and half the time will stall even after 5 min.
with choke on 3 mins
but once warmed up propper.say 10 mins drive
goes up to 900 when stationary..she needs a service poor thing.

Hmm she stays a little colder first thing now as water bypasses the thermostat
Check to see the thermostat is working, you can test them in boiling water.
