grantura cooling

[plasticpig72]

a friend of mine has just rebuilt/reconstructed a Grantura from almost nothing over a period of 3 years+.
The car will be used for Historic racing and we have some question about the best cooling setup.
What to connect and where.
It has a Swirlpot with rad cap near the windscreen and catch tank for coolant (historic regs).
Alloy rad. The engine is MGA with an Alloy cylinderhead + 2 dcoe webers.
The cicuit at the moment is: Thermostat Outlet to Swirlpot, Swirlpot to top of Rad, bottom of Rad Outlet to Waterpump.
Does anyone agree with the circuit.
Thanks in advance from the experts here

the Grantura is a mk2A and no swirlpot but an Expansion tank with Rad Cap. On the Expansion tank there is an overflow pipe to catch tank because of Historic Racing regs. It's hoped to be raced at Le Mans one day.
thanks for the help guys
