Moving onto valve adjustment, usually once valve is close ( with hyd lifters) you take up the slack, by turning push rod until there’s no slack, then go 1/4 or 1/2 turn what ever they recommend. It’s been a while since I’ve done hydraulic lifters so thats my vague memory. Its kind of hard to mess that up, only thing that could is if, even though you thought valve was completely closed, may not have been. So that would hold valve open, partially. Could happen on either intake or exhaust, so thats why I take the time to go though them again, just to check.
The other thing, with hyd lifters what I used to do, was put the lifter in a can of oil and pump it up. Because i’ve found that some times, if the lifter wasn’t pump up, now your adjusting it, taking up the push rod slack up, but it’s actually already depressing the plunger. Now you fire it off the lifter pumps up. But the valve isn’t completely closeing. But anyway definitely going with the studs and adjustable nuts is a plus, just assures a more solid adjustment
