Cast vs. Aluminum heads and bang for buck..

About 500 bucks to cover valves and machining ,guides , seats and all that..
I can build a set of iron J's in the 250cfm range.
If you have no heads to start with or can't get any for dirt cheap then maybe the aluminum head that's the way to go.
if the level of performance your building exceeds the cost effort or ability of a factory Ironhead then maybe an aluminum head is for you. There are iron heads that are comparable and or better then most aluminum heads for a small block Mopar. If the decision you've made on heads is an educated one don't feel bad about what you picked, this isn't communist russia..we can do it differently.
