Best Offster Rockers for RPM

I am considering moving the pushrod holes on my RPM heads to open up the pinch point. I would like to use reasonably priced, shelf rockers on this setup (Sub $1000 price point so T&D, Harland Sharp, Manton are not being considered). What offset would you recommend and why?
Here are the readily available offsets I can find-
0- Stock Small block
0.180- Stock Big block (Indy T/A)
0.350- Hughes Big Mouth
0.650- Offset Big Block

The 0.180 offest rockers seems like a good bang for the buck and avalible in stamped steel, stainless and ductile all for around $300. I'm just not sure that is enough offset to be worth the hassle.


I’ve traveled this road and I just curious how much cfm are you looking for??? Do you have any rocker arms now???
