POLYLOC MOTOR MOUNTS

Reviving this old thread. I’m looking for alternatives to the saggy Anchor original style mounts. I have a 400 hp 340 and TTI headers with a manual transmission. Just tired of the saggy mounts and headers knocking the torsion bars. Despite many hard launches on drag radials the rubber mounts haven’t torn but they’re definitely sagging and very loose it’s annoying. Will the poly mounts address this issue?
