I ended up with MP iron rockers (which were junk, BTW). Those had the correct geometry, but had .010" clearance on the shaft. I sent them out to have them bushed and they're OK now. I should have stuck with stamped rockers.
That's odd. I have a new set of Mopar iron rockers here and they only have .002 clearance to the shaft. They had alot of side slop (over .120") so I shimmed that up to approx. .025. They also have real good geometry.
