I would tend to agree that all things being equal you should be able to increase peak hp significantly with the AFR 205 heads.
Which is not to say the Roush heads are "junk".
In the MM&FF testing series the AFR 185 head out powered the Roush heads by 50+hp on the same test engine. (391 vs 448.).
The engine was a carbed 331 with the Comp XE274HR.
But I also don't think the 205s will reach their full potential with the cam you have.
