eq magnum head valve springs

Are the EQ heads a shaft mounted rocker or pedastal? (Guess I dont know the difference? I see some people putting rockers like chevys and fords (Stud mounted?) on some magnum builds...Can someone educate me.

Pedestal, la are shaft. The oe mag stuff isnt too bad. Ive got the stg 2 mag mopars with oe rockers, seems like anything below 500 hp shouldnt be super sketch.
