I looked those up & I LIKED what I saw!
May I ask, where did you purchase those Jesel followers from?
Checked JEGS.....they sell Jesel rockers for SBC, BBC, SBF, BBF but they didn't show anything for Ford Mod Motors 4.6L, 5.4L.
I know they're very expensive but they're also an excellent final remedy to this issue & they're rebuildable (I really like that part).
Appreciate any info given.
Bought directly from Jesel.
