Stud vs pedestal mount rockers
I am trying to help a friend in Europe who has a 5.0L 1985. He wants a pair of Edelbrock cylinder heads. Apparently, 2 types: one for pedestal mount rocker arms (#60379) and one for stud mount rockers (#60329). Unfortunately, I don't know the difference between these 2 types of rockers . Can you help ?
Also, what are the rail rockers (#60329 will not accept them) ?
An last , would you know if he has hydraulic lifters or roller lifters (this is to select a camshaft kit).
