Anyone running old school adjustable Rocker Arms on Eddy 60779 heads?

Hey Folks,

Getting my list of parts required to install the Eddy 60779 heads on the 340. Not really looking for rollers. I know Edelbrock indicates the heads were designed to accept the old style adjustable rocker arms when using a more aggressive than stock cam. I'm thinking about using the ones in the pic. Anything I should be aware of, any obstacles you may have encountered going this route? Any concern with old/used rockers? Not adverse to buying new, but will use the money elsewhere if possible.

Thanks in advance and I hope all you FABO friends have a fabulous holiday season!
