The Ford Barn

I have an original radiator which I have flushed and back flushed (several times), but still have an over heating problem. Checked and head gasket appears OK; compression runs about 55 per cylinder & no bubbles in radiator. Checked timing & is OK. Runs on the road 35 to 40 with no overheating, but checked temp & it is above 205, but not boiling over. Boils over if I push her 45 to 50. I'm considering a new radiator; Brassworks extreme touring 11 FPI or Brassworks Active driver 10 FPI. I'm confused whether I need to add a fan shroud &/or one way check valve. Also do I need to add a thermostat & if so how do I install it? Any suggestions would be appreciated. Big Dan
