Solid Roller Lifters on a Hydraulic Roller Cam?

You can also order "limited travel" hydraulic rollers. Morel offers that option, and I'm running a set if you dont want to go to the solids.
Or you can do as David Vizard describes. Set the hydraulic lifters before priming the oil system and the lifters are MT of oil. Bottom until the valve just lifts of the seat, back adjustment until the valve is back on its seat and back off 1/4 to 1/3 turn more. With proper valve springs you will not get pump up and they will work like tight lash at a fraction of the cost.
