On your deal I would buy and use the Comp Cams282S grind, part number 24-308-4, and install it at 103 to 105 intake lobe center and use the lash as recommended, maybe experiment with both .004 to .006 tighter and looser to see what sound and driving you like the most scope twocents
All the stock street hemi cams with mechanical lifters, 1966 to 1969, had .028 hot recommended lash work shruggy
Tightening them up .006 to .012 made them a lot quieter and helped the bottom end power work shruggy
