Most Nascar engines are currently using shaft mount, roller fulcrum, non roller tip steel rocker arms. A few are using roller tips on the same design. Toyota is no different.
They are not similar to the old chevy design. Stud mounted rockers haven’t been used for many years.

I was going to make a joke about the Def Leppard drummer, but I stopped myself.
