Iron heads vs Aluminum small block Chrysler .
I know this question has likely been asked a lot but anyone using the replacement NHRA approved aluminum heads are you seeing gains , or would you have not spent the money in retrospect? Pros and cons would be great to hear , I am looking at getting a set done .. thanks

I got a set I was going to use on a 360 build, but the intake port volume is too much for a 360. So they are sitting in my garage yet. Didn't want to cut the intake surface for NHRA Stock.

Re: Iron heads vs Aluminum small block Chrysler .
I think the aluminum heads would be great for SS where you can weld up the ports and reshape them. Not sure about stock unless it was for a big valve 340 with 2.02" intake valves. BB heads are worse with too big of valve sizes for stock. I suppose it depends on your wallet. It would be interesting to hear of the cost difference between prepped iron and aluminum heads.

Re: Iron heads vs Aluminum small block Chrysler .
It appears most real fast 340 Stockers have them now.
They require a lot of work to be successful and are not cheap!!
