Lifter bore modification for adjustables

[Mark's 37]

Got the 12"x3/16" drill bits (3 just in case) and have been going through the Tardel book looking at his modifications of the lifter bores. That is taking 1/4" off the inboard side of each upper lifter bore to allow better access for an end wrench. I know his book is recent but since the newer adjustable lifters have a taller bolt head for better access, is this still a good idea?
