They never said but I’m betting short side. When you start with the minimum and take more away what do you end up with. I never personally saw one but there are only so many places to remove metal if you don’t gain it by moving the pushrod my best set of Edelbrock heads with a stock pushrod location cc out at 195cc
If that’s the case then for these updated ones they would have needed to find castings that hadn’t been ported yet. I can’t imagine they would have welded on all the ports to get material back?
