Forget the high $$ high flow WP. Like you said, sometimes they do more harm than good.
Run a good quality 190/195 thermostat. And a quality 3 or 4 row radiator should be fine as long as it has a high fin per inch count.
I personally would PM or email Z50k2 and ask him what he uses. He has a FI 401 thats more than stock. I know he fought a heating issue a good while back, but has it under control now. Since he has been in the same boat, he'd be the one to ask.
