Comp Pro mag lifters

Why do you think this lifters are going to be any better than the ones you are replacing?
I recommend you research issues with hydraulic liftesr here on the forum before you spend any money.
I went with these because the cup seat is .040 lower than the regular comps and I wasn’t liking that most of the lifters were at zero lash when I bolted down the rockers with the adjusters backed all the way out. Also, I’ve done some reading and folks seem to have had good results and liked them.
