My decision was....
I just, less than a month ago. Had to make that same decision. I have the 781 ovals, in my 70 chevelle, and after talking to my engine builder, I was convinced that other than the weight saving, considerable power and reliability can be had with the 781s. I am by no stretch of the immagination, a skilled mechanic.. But if you have the ovals ported,polished,hardened seats. valves etc. You will be happy.. Im sure if you buy the alum. heads, then do the same mods, more power can be had. But dollar wise.. its your choice.. good luck phil
