I did not know there was a cast iron LS head. If I was still pursuing SS\CS I would have looked at that hard, but the RHS head, I believe, has way more potential, and several CNC programs for it. The set we had flowed 368 at .800, and 263 on exhaust for the pulling tractor, and we reached almost 16 to 1 compression. And we didn't spend an arm, and a leg getting there. The best set of bowtie, phase 2's we had did 297, and 244 exhaust, and the best we did on compression was 12.6 to 1. And, I spent an arm and a leg.
