If you are talking about using Poly on the LCA bushings there are several good threads about that here.
IMO, if you go that way, spend the money on adjustable struts rods. When I first rebuilt my front end I went Poly and OE strut rods. When I updated the front end I used Poly again, but I used adjustable strut rods.
At this point I think I’d use adjustable strut rods no matter what bushing materiel I was using.
Several others on here can explain much better why the ASR’s are better.
