Anybody ever convert solid lifters to hydraulic?

Looks interesting (except for the price). The 4 deg advance should give better mileage and low-end torque. I installed a hydraulic cam w/ similar lift in my 65 273 and used Rhoads lifters for better low-end. I have thought about similar for my 64 225, though it is harder to find performance hydraulic cams (those slant cars were ~1978+) and I don't know if any Rhoads lifters would fit. I am not a fan of adjusting valves.
