4.0 roller rockers

[coldair]

Who here has installed roller rockers on there AMC 258 i6 / 4.2l with the 4.0 head mod? Somewhere i read that the roller rockers from a AMC 304 will fit a AMC 258 i6 / 4.2l . but i cant find it again.

I thought about at the time I did mine but in the $600 range for what I was seeing was a no go.

Roller rockers are great at higher RPM. I don't know about you but I prefer low RPM torque. Sure, roller rockers don't hurt low RPM but I just don't think they are worth it for off-road use.
Just my opinion.
