Plugs fouling, left side only

After many attempts to jet my webers, and always ending up with oil/fuel fouled plugs on the left bank only, I think I need to cure the fouling before any further jetting changes. Intake gaskets have been changed ( the old ones WERE leaking on the left side only) Valve seals have been changed to vitons ( old ones were teflon) Oil fouling is less, but still there. Thinking of going to hotter plugs, presently autolite AR 3924.
Any thoughts/input appreciated.
Thanks,
Ted
