Herbert Solid Roller Lifters?

No experience in small mopars, but I ran Herberts in a 406 chevy with around .600 lift with comp stainless rockers. Never had any movement of lash, no problems at all.
(If I remember right, I paid around $125. It was a while ago, lol)
Edit, re-read op post. I ran the roller version, I don't think they had the bushed ones then.
