I had Indy SR rockers on with the .630, 264/268 roller in the coronet. They were on there with the .516/.524 lift hydraulic before that. They seemed fine after a year and a half with the roller.
I'm ugrading to 1.7 T&D's with the Victor mw heads on the new combo.
The indy rockers are now on the wife's 426 wedge with source heads and .525 hyraulic cam. Replaced the adjusters with a set from Smith Brothers.
