I install the Edelbrock RPM heads on the Olds 455. I paint the ARP Bolt heads to simulate the stainless steel look. I go over how I calculate rocker arm geometry with the use of a Harland Sharp rocker.

i know of people who reuse them fine but that's for their own vehicle and they know the risks. I do not know of anyone who would recommend it as being correct or safe to do unless you don't mind redoing the headgasket
I'm about to set up the same rockers. Going to use a cross line laser to set the 90 degree starting point.
Another question for you Hutch, I'm using hydraulic lifters, do they need to be pumped up with oil to measure pushrod length ?
Looks like pontiac blue wtf
my bad I forgot you are using adjustable rockers.
I see you did not add any preload on pushrod for lifter preload.
Another question for you Hutch, would that pushrod checking tool be correct for stock rockers as well? I see summit sell many different length checkers.
I believe you want 90 degree rocker to valve angle at half lift …. not closed position??
another good video in the series, thanks.
you better get those heads checked by a machine shop before installing.
lots of discrepancies have been found in specs
