valve spring retainers

LOL- AGREED.
When I bought the Hughes rockers I went and drank all the Kool-Aid and ordered there extra little bits and pieces. (which actually made harder)

The decision is if the "Kool-Aid" makes you healthier or kills you. (your motor actually)
I'll get a little cheaper on some things like a Carter fuel pump instead of an Aeromotive, but parts that keep the valves where they belong is not a place I'm willing to take chances with.
