I honestly cannot answer that. I followed the supplier's recommendations and it wasn't as good as a normal full travel lifter with plunger set half-way down.

Someone somewhere may have found a way to make this all work out but it was complex and risky enough for my situation to cause me to stop looking at it once I saw worse dynamics in an otherwise stable setup that would spin clean-clean to well above 8000 RPM.
