I was reading an article where Tony Mamo did an L92 head back-swap on an engine. Meaning, he took an L92 headed engine and swapped them with a set of ported 243 (ls6 style) heads and a matched cam and they picked up nearly 40 hp over the l92 headed cammed set up. The reason being is the flow and quench of the L92 heads are great.... for forced induction applications but for NA the LS6 head prevailed.
