Randy didnt do anything to the heads. They went mid 270’s @600 lift. They pretty much just bolted them on after a valve job.
Yes, i used the moroso adapter on Patricks dominator.

Yes I know they were purchased ported, I'm also sure Randy optimized the valvejob.
Did all three drag metrics improve? J.Rob
