"Everyone seems to hate them"? I don't think you'll get that here. The only thing about the 307 is it's small. But other than that it can be a nice engine. I'd rather have a 307 than a 305 any day.
If I had a 307 I'd bolt on a set of L30 305 Vortec heads.
Need an intake, SA rockers, center bolt valve covers. The payoff is a real good flowing head w/a chamber size smaller than a 350 head. Some info and photos of the L30 5.0d L Vortec head can be seen at NastyZ28.com Vortec Cylinder Heads: The Definitive Guide
