Put a little silicone (sensor safe) in the grooves in the cylinder heads where the "O" rings sit to keep them in place. You do have to be very careful not to let the intake slide when placing it or you could knock the "O" rings out of position. It is easier if you have another pair of hands and lower it straight down slowly onto the "O" rings without any sliding motion. I use silicone on the "O" rings which makes things more prone to slide around but after it is assembled, if everything is in position, is much less likely to leak. Use Never-Seize on all the bolts so maybe in the future if you ever have to go back in there you won't break any bolts.
