I have a 454 with a High Energy Comp Cam .526 lift ,280 Duration @.006, 230 Deg @ .050 , 110 Deg lobe sep and stock 781's.It will adventually be a full roller 496 with mid to upper .600 lift cam w/Brodix Race Rite heads.I want to install Harland Sharp 1.7 rollers on the 781's,can I bolt them on and go (after adjust)or will I need to do something else.Also,can I swap them over to the Race Rites ? I think they are both 7/16"
Thanks.

I run roller rockers on the oem 840,s.The only thing I did was upgrade to arp rocker studs.They are machined flat on the top of the stud for maximum bite with the polylock set screws.
