Yes, I measured this on mine. Many different lifter designs out there so that matters as well as the cam base circle.

Based on the hyd flat tappet cam I had, discussed how much room I had to decrease the base circle with the cam grinder and how much room I had from there for lobe lift without uncovering the oil gallery. With an MP hemi block, unbushed, .430 intake lobe lift I'm only about .020 away on each end from uncovering the oil gallery.
