I saw where someone was installing LS heads on SBF. Not seen any results. I'm not sure even why you'd want to, other than just because you can. A set of high end Windsor CNC heads will make as much power. A couple of years ago I dyno'd and tuned an 434 CI LS NXT (regular SBC block) with AFR Mongoose LS heads at just under 650 HP, I also did a 434 aluminum SBF with smaller Afr 205 heads and a much milder cam and it made over 600. I also just built a BOSS 302 for a Vintage Mustang race car. It made 550 Hp at 7500 rpm, with ported cleveland cast iron heads. Back to my point neither the Chevy or the Ford use a single OE part. Even the Boss 302 only used the Ford heads, everything else was aftermarket.
