My thinking was I could locate the bearings over the oil holes to help keep oil moving down the pipe to the #2 rockers, and somewhat help keep the exhaust rocker located, although where the pushrod passes though the head wouldn't allow much movement anyways. If it was an intake rocker remaining I would of had to remove both rockers, the offset would have made it impossible to keep located with zip ties.

That pic is after the 30 minute drive to the hotel, the zip ties wore well lol.
