Solid Roller Lifters on a Hydraulic Roller Cam?

I have run sol lifters on several hyd cams, no problem. I would NOT use any type of hyd roller lifter. The internals are the same size as that of hyd flat tappet lifters, but the load has been doubled in some cases. The 'fix' has been things like tighter internal internal clearances to prevent bleed/down/collapse. Then the smallest amount of debris jams the lifter....

I would use 0.006-0.008" clearance, hot. Lash the valves initially at 0.012" & get the engine up to operating temp. Quickly remove a valve cover while hot & measure the lash on an int & exh valve.
Let the engine cool down & re-measure. You will now have the correct lash for cold setting.
