Well here is one for you guys to chew on.
https://patents.google.com/patent/WO2002012682A1/en
My buddy who races a very competitive Mini uses silicon nitride lifters.
I know that others have not had good experience but his engines have been
overheated, run out of oil, regularly run to over 9000 RPM and he has yet
to ruin 1 lifter or wear out 1 cam...
Would love to figure out a way to have them made for Healeys.
