Roller rocker choice for 380 crate

The stock Magnum heads , peak out at around about .500"- .520" lift. I recommend , a good valve job & bowl blend. Or check out the "E.Q" heads.

are you sure on that number...My cam has .538 of lift on the exhaust side and I use to run it on stock heads all day long...I thought I heard somewhere that it was larger than that.
