I have seen a LOT of Mopar engines just plain RUINED by "tube and peen lifter bores" and drilled out passages
I have NEVER EVER seen a Mopar that failed because it was not drilled out in some way--never seen it where someone could prove that was what happened all that being said I am a 9/32" man when a hole needs the crud knocked out of it
Honestly all that stuff is just where old 4 speed guys were grabbing at straws to keep the crank in one when they were turning them so far beyond what they will stand that is was not funny--a good restrictor every now and then will help-- a bigger hole in a stock block eehhh...
Just my opinion--keep on drilling and screwing them up if you want
