Solid Roller Lifters on Hydraulic Roller Cam

I am currently using Morel solid roller lifters on a cast core Comp Cams hydraulic roller cam in a 1969 LA 340. No block or oiling mods.
No problems yet but I do not have many miles on it yet maybe 1000 miles
Are you using these particular morel lifters
