graphite is the wrong cam lube.
The right cam lube is Moly disulfide paste.
Isky Rev Lube

Graphite is not used in automotive engines.
The only place the Moly difsulfide paste (Isky Rev Lube) is used is on the camshaft lobes. Not on engine bearing.
use automotive engine oil as a assembly lube on engine bearings.
GM EOS is nice to add to your oil. Mix 50-50 with motor oil for a assembly oil.
Dump the rest in.
You do not need to fill the hyd lifters with oil. just oil up the outside and install.
Do not get moly disulfide paste all over the sides of the lifter. goes on the foot of the lifter and on the cam lobes only.
