cam not to big so spring seat and open is not very hi most aluminum rockers will do the job stud rockers i used. Crane golds . Harland Sharp. Scorpion.PBM andHowards .all will hold up good . the Crower.s are very nice. any rocker in this list will work if you get the mild lift right . you say you busted steel body a ultra pro magnum Comp rocker? check your valve train for coil bind . check push rods. i would send that rocker back to comp i would think they would want to look at it . i use this rocker in two builds looks good no come backs
