Rebuilt 302 casting heads available through Rockauto
Pardon my ignorance, what makes this head desirable
In my opinion...absolutely nothing.
When I was in college in Colorado, my Barracuda was my daily driver, had a mild 318 with some lightly home ported J heads and a small nitrous kit. It ran 13.9 at Bandimere (5800' altitude). I was
sold on the 302 heads by a local "mopar guru", so I bought a set, did my same light home port and put them on my car. To my utter disbelief my car ran
half a second SLOWER in the 1/4 mile (14.4 at Bandimere).
The 302's felt snappy driving around town, but the power was just not there compared to my other heads. I swapped heads back to my J's and sold those 302 pieces of crap. I would never pay for another set, unless I would building a completely stock motor with no power goals....which isn't going to happen.
Just my real world example, and opinion.
