I've got a set of 95 EJ22 heads, and I've been looking into swapping the roller rocker assyemblies into the head on my 91 turbo. Anybody else done this before?

I'm running one roller rocker head and one non-roller head on my EJ22 right now.

I believe roller rockers will swap because part numbers for some (unassembled) heads are the same between "roller" and "non-roller" years. Don't know if lash adjusters have to be swapped as well.

I haven't looked at the non roller heads yet. But the whole assembly from the roller head unbolts with 6 10mm bolts, bringing the rollers and HLA's out together, I figured just putting that all over onto the other head as one piece. I'll be having it apart anyways, doing a complete reseal/head gasket/ t-belt job before it goes on the road. As well as a few other "little" things...
