I was responding to the OP about canted-valve heads but I didn't know those SB Hemi heads had been around that long. Makes me wonder how much better they performed than whatever W-series heads were available at the time, if at all...
Good thing the G3 Hemi was made in such huge numbers though I picked up a 2014 5.7L a few years back for $600 with the usual bad cam lobe and lifter. Nothing a new aftermarket cam, lifters and SRT oil pump can't fix though.
