Ford 302 head swap to 351W

[Frap 54]

I know this has ben discussed in the past but I'm missing something here. I put a new set of 351W heads on my 72 ford 5.0. The heads I used had the non adjustable rockers, I over came that little problem. I have an over heating problem. I have to leave my heater control valve partially open to keep the coolant temp down below 195. I have had the heads off and pressure checked, no problems. I installed a new radiator, changed the thermastat. The engine didn't have a heating problem prior to this and only has about 5K on it. I have compared my heater hose routing to other similiar Fords. Please any ideas are welcome.

Which head gaskets did you put on ?

Well, he's half right - He is a newbie

If opening your heater control valve has ANY effect on engine temperature, then you're dealing with a minor problem. I bet your radiator is clogged or partially blocked.

We need more information though, is this only at low speed or at all speeds?
