I used my Canfield 220cc heads on a BLOWN 383 - made 625 hp and 581 tq on the dyno...

Heads all depend on camshaft - cam - compression - etc and what RPMS you want to make power at. 200's won't have much bottom end.
All it really has right now is bottom end, it made 310whp at 5500 with an RPM Gap and a Comp 268 cam. The heads are about 10-12 years old so they are the older style casting from what I understand.

Thanks for the dyno sheets, I'm surprised to see an engine as big as your 406 with 180 heads; I guess they flowed well enough though!
