Respectfully, I am saying that for a few reasons. Very few 800HP BS builds quite a few -1 builds. It takes a lot of hogging to match the MCS of a -1 as cast. Both heads need a valvejob as delivered. Also, the BS head gets REALLY thin when you try to raise the roof near the spring seat! The valve seats are too small to increase the intake valve size, the rocker anchor system on the Indy allows for bigger cams. There are no 900HP na BS engines let alone 1000HP BS engines.
