Heads for mild 360 build

I run the promaxx heads on my 360 build the engine builder told me by the time you have me rebuild my 2.02 j heads with hardened seats and any porting I would have more in my cast iron heads then buying the promaxx without having to port them and have way more flow I really like them and have no issues my builder bought them bare and built it to my hp spec very happy with the results
