I would NEVER run a race lifter on the street, they are too sensitive IMO and at a very minimum you really need adjustable rocker arms at that point.
It has been many years now and the Cam Motion cam and Johnson lifters for me have been an ideal setup. Yes I fought the LS1 valvetrain wars, skip the LS3- LS7 vavletrain wars (had a Challenger), and broke a LS7 lifter / Texas Speed cam setup, and now live with say 15 less HP but a long term still going mild ramp profile Cam Motion cam and Johnson lifter (non race) setup. I'll check preload in the next few weeks (lazy).

Which lifters from Johnson are you running? 2116,2126, 2110? I didn't think the gm race lifters was unstreetable since it seems nearly the same as an ls lifter in every dimension. But I did find a new issue that has been causing the issue.

I have the pan off and front cover, found out I missed the pin on the cam gear over advancing the cam causing all this bs. I assume that was knocking the lifters out of proper preload
