I don't know for aure but any head MoPar made after the W2 was aluminum for the 2 things that make then a choice over the iron and thats weight and repairability. That's it.

Yep thats the obvious parts that is great for us "amateurs" , heads up racing in classes where money and repairability is not even a question that has a set minimumweight is a whole different deal where the teams would do pretty much anything for even the slightest extra amount of power and if iron was any better they would run it thats for sure and its the reason im qurious about the statement.

Im not against iron heads at all i just dont get the whole claim that they make more power everytime and was hoping there was some real data behind it.
