Solid Roller Lifters on a Hydraulic Roller Cam?

Any reasons not to do it?
They are cheaper than hyd roller lifters and less likely to grenade. Seeing quite a few hyd roller lifter stories in the past couple years about bad quality internals and axles...
The cam I want to use is the cam I want to use and it's a hyd roller grind. Only looking for relevant answers. Thanks Mopartners!

No. Just no. Solid grind cams have "takeup ramps" built in to take up the lash gently. Hydraulic cams do not have this as they are not needed. You may get away with it for a while, even setting the lash fairly tight. Problem is you do not want the valvetrain to go into no lash where you loose valve seal. On the loose side can hammer components.
I get the idea you like the specs of the hydraulic cam, so run it with the matching hydraulic lifters, or look for a solid lifter cam that will give equivalent valve event timing and lift.
Any engine build is a compendium of give and take, so you want the cam you live with the lifters.
