What are they from? I don't know of any roller rockers made for the 4.0L that were 1.5:1 ratio. Usually 1.6:1 or 1.7:1.

Unless you can do a whole bunch of machine work they won't work. You simply can't bolt on any rocker.

1.6:1 ratio. However simply drilling and taping the boss for a stud is not the solution.

Sell them back and get a refund. The 350 SBC rockers won't work on a Jeep I6,

SBC rocker arms are way too short from the pivot to the valve tip. You'd have to relocate the studs closer to the valve on a 4.0 head platform to get them to contact correctly.
