For those interested. Adding head mounts to your setup helps reduce driveline movement under high torque applications as well as takes a lot of stress off your transmission bell housing. If the driveline of your build is in a tight space where you might worry about the driveline coming in contact with other components or if you’re looking to beef up your mounting points this is a fun option. My current driveline setup has 4 total points of mounting. Side engine, head mounts, top mounted th400 and top mounted transfer case. Everything will have poly bushing to help absorb the vibration and make it so it can move slightly but in general will be a more solid mount overall.
