Use the IC EC method + the up down pushrod method to set the preload on the rockers.
the spin method results in exccesive tight preload- lifter bottoming.

A big cam will need a modified timing curve or locked out timing as it needs a ton of initial timing
a stock distributor timing curve will not work with a racey cam.
what are the cam duration specs.

A final rocker preload set up will need to be done with the engine fully warmed up and idling.
loosen each rocker and retighten each 1/2 turn preload from 0 lash.
