Lifter seat height

In the middle of my 340 build, I've decided to go from a hydraulic cam to a solid. Since I've already ordered the custom length push rods for the hydraulic setup, I want to avoid buying new ones if possible. I'm using the PRW adjustable roller rockers. The Crane anti-pumps I have are 1.580 seat height. The Comp Cams solids are 1.79 or 1.63 seat height. Am I correct in wanting the 1.63 Comp Cam solids since they are closer to what the hydraulics are, and will most likely work with the pushrods and adjustable rockers I have now? Or am I totally off base on this? Thanks for any help.
