Thoughts on the 452 heads

I like the short turn on the 906 a little better. Both good heads though, and if I’m not mistaken the 452 have hardened seats.
I may be wrong, but it seems iron heads make more power versus aluminum at the same compression ratio, and flow numbers.
I pocket ported my wife’s 440 sixpack heads and did the 2.14/1.81 thing, it’s impressive and will run 11s in the Challenger, and they’re 452 heads.
If I wanted the weight savings I’d be thinking something aluminum, and aluminum water pump housing.
