Correct pushrod preload?

Used the search feature and finding different answers. I'm running a compcams hydraulic flat tapper lifter xe275hl cam. I converted my lifter to a solid by taking apart and shimming the inside. This is going in a stock stroke 360 for street use and was wondering after I set my adjustable pushrod length to 0 preload how much of a theoretical turn should be made and about what that equals in additional length so I can calculate what length pushrods to order. Thanks guys.
