Seems like about a dozen years ago, I had a copy of Chevy High Performance magazine that had a great chart in it that showed the runner volume, combustion chamber CC and other vital specs of SBC heads. Hmmm... thinking about it, it might have been as far back as the late '80s that they had that chart. :
It's a long shot, but does anyone remember it? And it's an even longer shot, but does anyone know the runner volume of -291 double hump heads?
Mortec has the specs for the -461 and -461X heads, but no others. I'd like to compare them to the -291 heads I have.
