Aluminum heads $ per HP?

That was a bad example..especially coming from me.I quoted info from a test i saw that also paired identical small block chev heads in both aluminum and iron and test results in the one i read the iron made 8 hp more.I had no first hand experience and passed along info i read.This is thing i always complain about from responders...My Bad!
but aluminum does allow you run higher cylinder pressure.Yes above the .480 more .490 cam you would be comparing apples to oranges.In HP output ( above 400) you would need a big cam to justify the expense.But when it's a hobby does it matter?
