I've used the Moroso gaskets with the Indy cast covers for years without any problems but the MP valve covers ruined the Moroso gaskets almost immediately. I switched back to the thick black FelPro gaskets for the rest of the dyno session.


Andy I have those gaskets and MP valve covers and haven't had any issues. My MP covers are at least 10 yrs old. Do you know if MP may have changed the valve cover. Not questioning what happened to you just wondering out loud. Thanks


Ok
