BB chevy aluminum head weight penalty

I'm very curious for the sake of discussion and the opinions and thoughts of all you who race rectangle port combinations IE L-78,L-72,L-S6.Is the performance improvement of the later technology aluminum head worth the 10 horsepower/weight penalty? Am I wrong in thinking that surely they would make more HP than the original alum.head ?
P.S.Who is the go to person to do a set of Stocker heads ?

A person who wants to learn..THANKS to you all.
