Believe it or not I am left handed 😊; I finished the job and the engine runs great it’s just such a hassle. In the video I saw the guy did both banks in under 10 minutes, took me 3 hours. I love to find out what he has for adjusting screws.

Helps to be lefthanded.

Using all your strength trying to hold the screw driver left while turning the box wrench in the opposite direction is a contest I assume you have not yet experienced.

Neat tool.  Eliminates the need for feeler gauges (except initially), at least for the average motorist not requiring ‘racing caliber’ lash precision.  Indicator dial works on the ‘screw micrometer’ principle.

You might try .019-.022 and leave feeler gauge in place while tightening lock nut. If you can remove the feeler gauge, you should be in the ballpark. I don't mean to be a wise guy, but you do realize you have to use the screwdriver to keep the adjuster from turning while you tighten the nut? Valve adjustments are pretty much a thing from the past and don't apply to most modern cars, foreign makes possibly excepted.Not everyone has done it.I grew up around motorcycles that used screw adjusters and still prefer them to shims, even though they have to be checked more often. 

I concur with Charlie. Mummert has both types of adjusters, but those/w nuts are more expensive. I think Crane has/had the self-locking adjusters (no nuts) that got good reviews. 

The jam nut adjuster is one of the two methods of holding the adjustment.  This requires a wrench and screwdriver (or allen wrench for aftermarket rocker arms or screws).  The other is with interference fit adjuster screws, which only require a socket or wrench.

The interference adjuster eventually becomes loose and the jam nut adjuster is best.  It does take some practice.

Thanks guys, but I may have found what I’m looking for from Summit Racing. I have to do a little more research.
