i wish mopar guys weren't so "scared" of stud mount rockers. That IS the one thing i prefer about the magnum heads we use. we can use common SBC style rockers. not $1200 rockers.
The Harland Sharp Mancini ones were like $560 with shafts/holddowns and bolts... not a bad deal really.. I'm not afraid of stud rockers, just going with what works on the heads :)
