I used Locktite on the Timesert, just to lock it in place before screwing the rocker post into it. I did this because I wanted equal thread engagement in the Timesert and rocker post. The Locktite just kept it in the position I wanted. The other thing I would recommend is blocking the oil hole and groove in the lifter pocket. I used a little JB weld after cleaning all the oil out of the oil hole and slot. You want all of the oil going to the head ending up on the cam, not some of it leaking around the rocker posts back into the sump. The one I did was a new engine build, so when I primed the engine, I checked that none of the rocker posts were leaking oil.
